Between the chemical balancing and cleaning, every pool owner is well aware of the challenges that are entailed in the task of opening a pool up for the season, and even harder if setting up a pool for the first time. In most parts of the world, pools are seasonal, with climates necessitating their closure for winterization during the colder periods of the year. Reopening them ends up being a big to-do even for the most seasoned pool owner.

To keep pool water clear and pH balanced requires at times taxing pool maintenance every week. If maintenance is a challenge, revitalization of dormant pools ups the effort necessary to another level. When the pool is initially filled with water, getting it suited with the right chemicals from the start is essential. If you start successfully, weekly maintenance becomes less burdensome. But if the chemical balance is not achieved from the get-go, the weekly work becomes a challenge to fix the water rather than simply maintain its levels.

Before you decide on what chemicals your pool needs, you need to figure out a few things, primarily what type of water your pool will contain. You can get all of the information you need by testing the water thoroughly. Let’s discuss the start-up chemicals you need to get your pool started right.

Pool Start Up Chemicals

As noted earlier, your first objective is to study the water that will be filling your pool. Presumably, before filling it with water, you took the time to clean your pool. Doing so will reduce the number of potential contaminants that your will need to concern yourself with during the process. You can also schedule a pool maintenance service to confirm that the water in the pool will be chemically balanced to being with.

If you have any aspirations of filling the pool with entirely purified water, we urge you to abandon the notion before you attempt it. It would be costly and absurdly ridiculous to even try it. Even filling the water from a fresh-water source is not going to result in perfect water. No matter how you slice it, your pool water will require treatment.

Before you know how to treat it, you need to know what you are treating. For that, you have to test your water. While this can be done with a small test, performing a full water test is the better option. That way, you are aware of everything that needs to be addressed in order to set the pool up correctly.

Your “Perfect” Chemical Balance Goals

Not all aspects of the pool water may be off-target, but those that are will need chemical treatment. To know what chemicals you need to use to balance the chemicals of your pool water at the start, you will need to know the target ranges you want to be inside of for the various categories. Anything outside of these ranges will need to be addressed.

  • pH (ideal range between 7.2 and 7.6)
  • Alkalinity (ideal range between 80 – 120 ppm)
  • Chlorine (ideal range 1 – 3 ppm)
  • Calcium Hardness (ideal range 180 – 220 ppm)
  • Cyanuric Acid (ideal range 30 – 50 ppm)

If your pool water hits inside of all those ranges right away, you have some serious luck on your side and you should grab a lottery ticket immediately. If you are that lucky, congratulations, your pool is ready to go without any effort. However, this is very unlikely to happen. In most realistic situations, it is a very good idea to make note of the actual readings that you get upon testing your water and keep a record to help you figure out what chemicals will be needed later.

What Chemicals Do I Need to Start My Pool?

Once you have the necessary chemical data, you can begin to address your pool water’s chemical needs. Dumping every chemical in the water will solve nothing and only create more problems. Every chemical added should be making a significant push to get the chemical levels into their desired ranges. If you add too many chemicals or too much of certain ones, you can cause a chemical interaction.

Now, let’s discuss the chemicals you might need to add to your pool’s water depending on what chemical range you are seeking to adjust.

1. Alkalinity

If your test showed that the water’s alkalinity was out of range, regardless of whether it was too low or too high, you will need particular chemicals to adjust it. This chemical should be added to the water first after start-up, assuming it is necessary because it can have severe effects on the water’s pH level. If you do not address the alkalinity first, you may balance your pH only to ruin it with the alkalinity chemicals, and have to spend more time and resources on it later.

If your alkalinity levels are too low (under 80 ppm), you will need to use an alkalinity booster. This should be added in safe increments, as you test the water to make sure that the alkalinity is within range. If the problem is that the alkalinity is higher than 120 ppm, you will need to apply a pH reducer to lower it. Obviously, this will lower your overall pH, so as noted earlier, this adjustment should come first.

2. pH

To keep your pool in working order, keeping your pH balance is pivotal. When the pH is off, the chlorine will not work properly, leading to excessive chlorine and the water being unsafe for use. The pH level should be the second thing to be adjusted, and you are looking to have the pH land between 7.2 and 7.6, as that is the ideal range for safe water and the subsequent chlorine addition.

You can use the same pH reducing agent as you did to lower the alkalinity earlier if the pH is too high. If it’s too low, you simply need to add a pH booster to your pool. When the pH is over 7.6 it is too acidic, which means that the pool’s water is not suitable for swimming as it is too corrosive. If you take too long to adjust the pH problem, your pool’s maintenance will be impacted.

Regardless of the increase or decrease of the pH, you will need to regularly test the water and adjust the pH if necessary.

3. Calcium

Once the pH and the alkalinity are adjusted, the calcium levels (hardness of the water), need to be addressed next. Calcium hardness does need to be included in your pool start-up chemical maintenance, and should also be regularly assessed to see if it needs adjusting during your weekly checks.

If your calcium levels fall below 180 ppm, you will need to add a calcium hardness booster. The one benefit of calcium adjustment chemicals is that they don’t interact with or counteract some of the other chemicals, but you should certainly aim to get the calcium in the right range into your ideal range.

If the calcium is too high, you will need to use muriatic acid to lower it. However, this chemical requires caution as it not only alters the calcium, but also the pool water’s alkalinity. That means that once your calcium hardness is in a good place, you will want to test the water to make sure the alkalinity is still at the desired levels. While it is a nuisance of an activity since you already adjusted the alkalinity earlier, in the long run, it is worth the effort.

4. Cyanuric Acid

The next step is actually a bit of a rarity in terms of the chemical composition of pool water to be tested but is a good idea to test when setting up your pool: cyanuric acid. New pools are likely to not be affected by cyanuric acid as it is something that forms as a byproduct of chlorine being added to pool water over time. Once it does accumulate, it does affect the water quality though. While you are unlikely to have to deal with this at the start, it doesn’t hurt to test for it just in case.

The chemical treatment depends on what type of chlorine you use as well. To adjust the chemical standing of cyanuric acid you will need to add stabilizer, but only doing so if you are using free chlorine, which isn’t the type that most people use these days anyway. If you do need to add it, remember to bring the levels of 30ppm to protect the quality of the chlorine. Not doing so will result in free chlorine reacting to sunlight, which will degrade its efficacy and cause the pool to get dirty quickly.

5. Chlorine

Finally, there is chlorine, the most important chemical that you will use to keep your pool water safe and clean for swimmers to enjoy. However, over chlorinating your pool is unsafe as well, as excessive chlorine will sting and damage the skin of those who swim in the water, so it is something you should be cautious to avoid. Yes, chlorine is not the nicest smelling chemical, but the tolerance of its smell is worth it to have a pool full of clean water.

Application of chlorine to raise its levels should be done quickly. It is a shock treatment approach that cleans your water without throwing off the levels of the other chemicals in the process and degrading their effectiveness.

Always follow the manufacturer’s instructions for chlorine dosage when adding it, and make sure you are well versed in when additional chlorine is needed. Chlorine is very effective at its job, but only when used correctly.

Chemical Balancing Is Essential For Pool Start-Up

Chemical treatment of pool water may take time at start-up, but it is nowhere near as long as it would take to start needing to fix the water quality if it isn’t done (or not done properly). You can save yourself a lot of headaches by cleaning your pool before filling it. The cleaning process removes a significant amount of contaminants, so when you test your pool water, your chemical balances will likely not take too long to balance.

Testing pool water could be taxing work and too complex for some people, which is why they take advantage of pool specialty services when they start up their pools at the beginning of the season and close them down at the end. This helps the pool start off with the right chemical balancing work and only require routine maintenance in that regard throughout the season. Other pool owners take on the task themselves. It is not rocket science, but it does take accurate testing and precision to balance things out right in order to enjoy a safe and fun summer pool experience.

Bromine is a chemical element that is used in swimming pools to help disinfect the water and prevent algae growth. It is usually added to the pool in tablet form, and dissolves slowly into the water to provide ongoing protection. Bromine is a very effective sanitizer, but it can also be harmful if not used correctly.

In this blog post, we will discuss what bromine is, how it works in pools, and some of its benefits and drawbacks. We will also provide information on how to properly use bromine in your swimming pool. So, if you are curious about this lesser-known pool chemical, keep reading!

What is Bromine?

Bromine is a chemical element with the symbol Br, and atomic number 35. It is a heavy, volatile, reddish-brown fuming liquid at room temperature that evaporates readily to give off choking brown fumes containing bromine.

Bromine compounds are produced by reacting hydrogen bromide with chlorine or water. About two-thirds of the world’s bromine is produced from Dead Sea brine. The rest of the world’s production occurs naturally in underground deposits in Russia, China, and the United States.

Once used as a medicine and in photographic film, bromine has become an important fire retardant, drinking water disinfectant, mosquito control agent, and component of automobile engine coolants. However, it is a source of pollution, and its use raises environmental concerns. Some countries have banned its use while others continue to allow or require its addition to consumer products.

Bromine in Pools: A Brief History

The use of bromine in pools dates back to the early 20th century. At that time, chlorine was the primary disinfectant used in pools, but it was found to be ineffective against certain types of bacteria.

Bromine was introduced as an alternative and quickly proved to be more effective than chlorine. However, bromine has several disadvantages. It is a strong irritant and can cause skin and eye irritation.

As a result, chlorine is still the most popular disinfectant used in pools today. However, bromine remains an important part of pool chemistry and is often used in combination with other disinfectants to provide the most effective pool sanitation possible.

What is Bromine Used for in Pools?

Bromine is a chemical element that is often used as a disinfectant in pools. When added to water, bromine helps to kill bacteria and other microorganisms that can cause disease.

In addition, bromine can also help to control algae growth and prevent the formation of harmful chlorine byproducts. As a result, bromine is an important part of keeping pool water clean and safe for swimming.

While bromine is effective at disinfecting pool water, it is important to use it safely. When handling bromine, be sure to wear gloves and eye protection. In addition, be careful not to spill or splash bromine solution, as it can cause irritation to the skin and eyes. By following these safety precautions, you can help ensure that your pool is a safe and enjoyable place to swim.

What Does Bromine Do in a Pool?

Most people know that you put chlorine in a pool to make the water clean. But you might not know that chlorine isn’t the only chemical you can use to clean pool water. Bromine is another chemical that’s often used in pools. So, what does bromine do in a pool exactly?

Bromine works in a pool in much the same way that chlorine does. It helps to kill bacteria and other harmful organisms that can make people sick. Bromine is especially effective at killing algae, which can sometimes grow in pools if there’s too much chlorine.

That doesn’t mean that bromine is better than chlorine, though. Both chemicals are important for keeping pools clean. In fact, many pools use a combination of both bromine and chlorine to make sure the water is as clean as possible.

Is Bromine Better Than Chlorine in a Pool?

When it comes to keeping pools clean, it’s hard to say if bromine is better than chlorine. Both bromine and chlorine are effective cleaning options. Both substances kill bacteria and prevent the growth of algae.

Chlorine is a stronger disinfectant than bromine, so it is often used in areas where there is a higher risk of contamination. Bromine is less likely to cause irritation, so it is often used when people are more interested in swimming comfort. Bromine tablets are also a lot more expensive, which is another reason why it is less used than chlorine.

Ultimately, the decision of which chemical to use depends on the specific needs of the pool.

Owning a pool isn’t all fun and games; it takes time and effort to achieve crystal clear water. One of the fastest, most effective, and most popular ways to address a dirty pool is to shock it. However, many homeowners fail to realize that the cause of cloudy water can sometimes be the shocking process itself.

If you shock your pool and find it murky afterward, don’t panic! It happens sometimes. Once you find the cause, you can determine how to fix it. This article will dig into the logistics of shocking your pool and how to clear out the lingering cloudiness.

What Does Shocking a Pool Mean?

What Does Shocking a Pool Mean

Shocking your pool involves pouring chemicals into the water to raise its chlorine level. The goal is to increase the chlorine level enough to kill contaminants like algae, bacteria, and chloramines, which will usually clear out any cloudiness in the water.

However, don’t let the strong smell of chlorine trick you into thinking your pool is clean. In fact, chloramines — the compounds that are formed when chlorine combines with oils, sweat, and urine — are the cause of this scent. You want your pool to be as odor-free as possible.

To shock your pool properly, it is essential that you understand the different types of chlorine, listed below:

  • Free chlorine (FC): “Free chlorine” refers to the amount of all active chlorine types present in the water. Ideally, it should remain between 1 – 3 ppm.
  • Combined chlorine (CC): “Combined chlorine”, on the other hand, measures the used chlorine. While used chlorine is still in the pool, it has a weaker sanitizing power than FC. Keep this level below 0.2 ppm.
  • Total chlorine (TC): This number refers to the sum of the FC and CC in your pool.

When your free chlorine level hits zero or your combined chlorine level reaches 0.5 parts per million (ppm), it’s time to shock your pool. The goal of shocking your pool is to reach breakpoint chlorination, which is when you have enough free chlorine in your pool to kill chloramides.

Why Does a Pool Get Cloudy After Shock?

Why Does a Pool Get Cloudy After Shock

You shock your pool to clean it, but one of its potential side effects is leaving the water cloudy. When the water’s chemical and mineral levels are out of balance, adding chlorine can cause a reaction, which can cause this cloudiness. However, there are other reasons why your pool can get cloudy after a shock session. Here are some of them:

Filtration Issues

Contrary to popular belief, shocking the pool is not enough to keep it in tip-top shape. You also need a high-quality filter that works properly to achieve your desired results. If your filter is not up to par, it doesn’t matter how many times you dump chlorine into your pool; you will never achieve crystal clear waters. After all, chlorine can kill any contaminants in your water, but it cannot remove them from your pool for you.

High Calcium Hardness Levels

Another factor to consider is the water hardness in your area, as hard water will become murky much faster. For instance, if you live in an area that releases tap water with over 500 ppm hardness, pouring calcium hypochlorite to it adds 5 ppm for each pound of the chemical. Ideally, you should aim for 120 to 220 ppm hardness levels to keep your water crystal clear.

High pH Levels

Since shocking a pool involves massive doses of chlorine, you can expect various reactions from the process. For instance, if you have high levels of the wrong chemicals, mixing them with chlorine can cause your pool water to turn milky after shocking it.

If your pH level goes beyond 7.6, you’ll waste your chlorine. It’s best to look for a low pH level between 7.2 – 7.4 during the shocking process.

High Levels of Cyanuric Acid

Cyanuric acid — also referred to as CYA or stabilizer — is a common chemical used by many homeowners to prevent chlorine loss. However, too much CYA can cause the water to turn cloudy when you shock it. Check your CYA level monthly to ensure that it stays below 50 ppm.

Lack of Pool Clarifier

A pool clarifier gathers particles that turn your pool water cloudy and binds them together to create larger granules that your filter can catch. Using a clarifier after shocking your pool is crucial to keeping the water clean.

How to Clear a Cloudy Pool After Shocking It

How to Clear a Cloudy Pool After Shocking It

Usually, any cloudy pool water that happens as a result of shocking is temporary. You typically don’t need to do anything but wait, as it should clear up overnight. However, if you still have a murky pool after 24 hours, here are some potential causes of your pool’s prolonged cloudiness and how you can solve these problems:

Problem: Filtration System

If you want to say goodbye to cloudy water, check your filtration system. Make sure it is clean and free of buildup, your skimmer basket or pump bucket is cleared of debris, and your filter media is not worn out.

Additionally, run your filter for longer than you typically would. When handling a cloudy pool, run the water through the filter system anywhere between 8 to 12 hours per day.

Problem: Unbalanced Water Chemistry

When your water’s calcium hardness, pH, and alkalinity get too high, they can affect your pool’s plumbing. This can cause quite an array of issues in your pool, from poor filtration to bacterial growth. The ideal levels for the above are as follows:

  • Calcium hardness: 120 – 220 ppm
  • pH: 7.4 – 7.6 ppm
  • Alkalinity: 100 – 150 ppm, ideally 125 ppm

Next time, before you shock your pool, check its chemical levels first. Once you balance them out to the levels above, your filtration system will get your pool back to its usual clarity.

Problem: Low Chlorine Levels

If you shocked your pool and didn’t achieve the desired results, you might not have used the right amounts of chlorine. Without enough of this chemical, pathogens and bacteria can still form in its presence, causing the water to get cloudy. The appropriate amounts of chlorine also sanitize the water from bodily contaminants like sunscreen and sweat.

Before you shock your pool again, test your FC, CC, and TC levels. Next, remove excessive debris, like leaves, as they can cause chlorine levels to drop drastically. Afterwards, add enough chlorine to achieve breakpoint chlorination, and then give your pool time to adjust. The cloudiness should clear away within a day.

Frequently Asked Questions

Why Do Pools Get Cloudy After Shocking?

Having cloudy or milky water after shocking is not always a bad thing. Sometimes, adding water after the process will get your pool cleared up in about an hour. As long as your pump and filter are running accordingly, you shouldn’t have a problem clearing up the water.

If you add an algaecide, this may be making the pool milky, because it contains copper. This milky look can last for about one day without being a cause for concern.

However, if the cloudiness persists after 24 hours, check your filter and the levels of your chemicals, especially the chlorine levels. You might need to fix your filtration system, add some chemicals, or redo the shocking process to clear the cloudiness from your pool.

Can Too Much Shock Make a Pool Cloudy?

Yes, too much shock can make the water cloudy, but only temporarily. As your solution kills contaminants, you might see a dishwater-like shade on your usually crystal-clear pool. However, it shouldn’t be a cause for concern; this happens to the savviest of pool owners all of the time!

If you’re concerned about your shocking methods, know that it is essential to use the right shock type and amounts to achieve the desired results. If you have high chlorine levels and cloudy water simultaneously, the problem is not with too much shock; you have to do some investigating to find the underlying issue to address it. It could be your filtration system, chemical balance, or even mold growth.

How Long Do Pools Remain Cloudy After Shocking?

If you recently shocked your pool and now see a cloudy appearance, it could be a normal part of the process. In most cases, a murky pool after shocking is only a temporary setback that clears itself up within 24 hours.

If it’s taking too long, you can try filtering your pool and adding some clarifier to speed up the process.

Are Chlorines and Shock the Same?

No, they are not the same. Some shock brands contain chlorine, such as Calcium Hypochlorite, but others do not.

However, chlorine is a necessary sanitizer for maintaining a healthy pool. You can use it in high doses to shock your pool and raise the chlorine levels to achieve clear water.

How Soon Can You Swim After Shocking Your Pool?

Generally, it’s safe to use your pool again 24 hours after you shock it. However, it’s best to check the water’s chlorine levels before jumping in. Make sure it’s at 5 ppm before you swim, as too much chlorine can be uncomfortable or even dangerous for swimmers.

Final Thoughts

Shocking your pool is the best way to kill any contaminants like chloramines from your water. When left unchecked, these compounds can cause or aggravate respiratory problems like sinus congestion, choking, wheezing, asthma, and more.

It’s best to shock your pool once per week to maintain your pool’s health. Remember that it’s normal for the water to look cloudy after shocking, but for only about 24 hours. If you filter your pool water and add a clarifier but you still don’t achieve your desired results, you might be overlooking an underlying cause.

For instance, your filter could be faulty, or your pool’s calcium hardness, pH, and CYA levels might be out of balance. In such cases, the best thing to do is check. Test your filter and test the water for chemicals to determine the cause of the cloudiness.

The water in your pool is a complex balance of chemicals. If the pH of your pool drops below 7, it can wreak havoc on your pool and result in costly maintenance.

This post will cover what pH is exactly and why it’s important for pool chemistry. In addition, we’ll dig into what causes low pH and share a few different solutions on how you can raise it.

What is pH in pool water?

What is pH in pool water

The pH in pool water refers to the acidity or alkalinity of your pool water. This measurement is based on a scale from 0-14, with 7 being neutral. A lower pH indicates acidic water, while a higher pH indicates more alkaline water.

Maintaining proper pH levels is critical for many aspects of pool care. For example, pH affects:

  • The overall comfort of swimmers
  • The efficiency of your pool’s filtration system
  • How well pool chemicals work
  • The lifespan of your pool equipment

Why is pH important in a pool?

Why is pH important in a pool

pH directly impacts how well your chlorine works. If the pH in your pool is too high or too low, your chlorine will be less effective. This means your pool will be more susceptible to algae and bacteria growth.

In addition, the pH of your pool water can affect the comfort of swimmers. Swimmers may experience eye irritation, skin dryness, and scalp itchiness if the pH is not properly balanced.

What causes low pH in a pool?

What causes low pH in a pool

There are a few common reasons why your pool’s pH may be low. For example, if you have hard water or rainwater runoff in your pool, these can both cause the pH to dip below 7.

Low pH can also be caused by overgrowth of algae and bacteria. As these organisms grow, they release waste products that lower the pH of your pool. If you notice an increase in algae or bacteria growth, it’s important to address this as soon as possible.

What is the best way to raise pH in a pool?

Commercial Products

There are a few different options available for raising the pH in your pool. The easiest option is to use a granular or liquid pool pH increaser. These products can be added directly to your pool water and will quickly restore proper pH levels.

To prevent future imbalances, you may also want to invest in a pool chemical controller. This device will automatically add pool chemicals to your water, keeping your pH levels in check. This is a great option for busy pool owners who don’t have the time to constantly monitor pH levels.

Naturally with Baking Soda

If you want to go the cheaper route, the next best way to raise your pool’s pH is by adding a few simple household ingredients. Baking soda, also known as sodium bicarbonate, is a great choice for raising pH levels. Just add one pound of baking soda per 10,000 gallons of pool water to raise the pH by 0.2 points.

Ultimately, there are many different ways to raise your pool’s pH. Whether you choose to use a commercial pH increaser or a simple household ingredient, it’s critical that you take action if your pH levels drop below 7. By keeping your pool’s pH in check, you can ensure a safe and comfortable swimming environment for everyone.


Maintaining proper pH levels in your pool is essential for many reasons. Not only does it affect the comfort of swimmers, but it also impacts the efficiency of your filtration system and the lifespan of your pool equipment.

If the pH in your pool drops below 7, there are a few different ways you can raise it. The easiest option is to use a commercial pH increaser, but you can also add baking soda to your pool water.

By taking action to raise your pool’s pH, you can ensure a safe and enjoyable swimming experience for everyone.

If you’re new to owning a pool, you might have a multiport valve on top of your filter with a number of settings to choose from. One of the available settings is the “rinse” option.

In the below post we’ll tackle a number of common questions surrounding this setting. We’ll also help you understand how it’s different from other options like backwash and waste.

What does rinse do on a pool filter?

The rinse setting on a pool filter is used to clean out debris and other impurities from your pool water.

It works by cycling the water through the filter multiple times in order to remove any waste or contaminants that have built up over time. This can help keep your pool looking clear and sparkling, while also reducing the risk of bacterial growth and other problems.

When do you rinse a pool filter?

When do you rinse a pool filter

Rinsing a pool filter is typically done after backwashing. This is because backwashing can cause the filter to become clogged with debris, which can then reduce its efficiency. Rinsing the filter will help remove any debris that has been left behind and restore the filter to its original condition.

It’s also a good idea to rinse your filter periodically throughout the season, even if you haven’t backwashed yet. This can help prevent the buildup of waste and keep your pool looking its best at all times.

How long should I rinse my pool filter?

How long should I rinse my pool filter?

The length of time that you should rinse your pool filter will depend on a few factors, including the type of filter you have and the amount of debris build up.

As a general rule, you should rinse your pool filter for approximately 1-2 minutes. This will give the water enough time to cycle through the filter and remove any impurities that have been gathered.

If you have a lot of debris in your pool, you may need to rinse for longer than 2 minutes. In this case, it’s best to start with a shorter rinse time and then increase it as needed.

Some pool filters come with a glass gauge that can help you determine when the filter has been rinsed long enough. Once you start to see clean, clear water coming out of the filter, you know that it’s been rinsed effectively.

How often should I rinse my pool filter?

How often should I rinse my pool filter

The frequency with which you rinse your pool filter will depend on a few different factors, including how often you use your pool and the level of contamination in the water.

If you’re using your pool frequently, for example, it may be necessary to rinse the filter more often. This is particularly true if you notice that the water is starting to look cloudy or if debris starts to build up in the pool.

On the other hand, if you’re not using your pool as often, you may be able to go longer between rinses. A good rule of thumb is to rinse your filter at least once per month, but more frequently if necessary.

What is difference in backwash and rinse?

What is the difference between rinse and waste on a pool filter

The main difference between backwash and rinse is that backwash is used to clean the filter itself, while rinse is used to clean the water.

Backwash is typically done when the filter becomes clogged with debris and is no longer able to function properly. This setting will flush out the filter media and restore it to its original condition.

Do you have to rinse after backwashing a pool?

In most cases, it is recommended that you rinse your pool filter after backwashing.

This will allow you to remove any debris or impurities that have been left behind and help restore the filter to its original condition. Depending on the type of filter you have and how dirty the water is in your pool, you may need to rinse for longer than usual after backwashing.

What is the difference between rinse and waste on a pool filter?

What is difference in backwash and rinse

The main difference between rinse and waste is that rinse will recycle the water back into the pool, while waste will send the water down the drain.

Rinse is typically used when you want to clean the water without losing any of it. This setting will cycle the water through the filter multiple times in order to remove any impurities that have been gathered.

Waste, on the other hand, is used when you want to get rid of the water in your pool as quickly as possible. This setting will bypass the filter and send the water straight down the drain.

You should use waste if there is a lot of debris in your pool and you need to get rid of it quickly. You should use rinse if you want to remove any contaminants and keep the water clean, or if you recently backwashed your filter.


Most of the time your multiport valve will be set to filter. But that doesn’t mean you won’t find a need to turn off your pump and set your filter to rinse.

It’s an often-overlooked setting but provides an important function on pool maintenance. If you find that your pool water is starting to look cloudy or that there is a lot of debris in the water, it may be time to rinse your filter. And if you’ve recently backwashed, rinsing will ensure that all of the impurities have been flushed out and that your filter is restored to its original condition.

If you have a pool, then you know that your filter is necessary for maintaining the water quality. But how good is your filter at doing its job, and what should the pressure be?

In this article, we will go over some tips to help you determine what your pressure gauge should read. We’ll also share how to determine why your pool’s pressure might be too high or low.

What is a pool filter pressure gauge?

What is a pool filter pressure gauge?

A pool filter pressure gauge is a device that measures the strength or PSI (pounds per square inch) of the water flowing through your swimming pool filter.

It can help you determine if your filter is performing optimally, or if it needs to be adjusted or replaced. The ideal pressure for a pool filter will vary depending on several factors, including the size and type of your pool, the type of filter you have, and the operating conditions.

What PSI should pool filter be at?

What PSI should pool filter be at?

The pressure in your pool’s filter should be between 10 and 20 PSI. If it’s lower than 10, the dirt and debris won’t be filtered out properly. If it’s higher than 20, your filter will be overworked and could break.

Why is the pressure high on my pool filter?

Why is the pressure high on my pool filter

If the pressure in your pool filter is high, it could be because of a few different reasons. Maybe there’s a leak in the line or the multiport valve isn’t working properly. It could also be that you need to backwash the filter.

Why is the pressure low on my pool filter?

Why is the pressure low on my pool filter

There are also a few reasons why the pressure in your pool filter might be low. It could be that the valve is open too far, or there might be a leak in the filter. It’s also possible that there’s something blocking the flow of water, like a piece of dirt or debris stuck in the pump.

How to tell if my pool filter is working properly?

How to tell if my pool filter is working properly

To check if your pool filter is working properly, you can use a few different methods. One quick way is to look at the pressure gauge. If it’s in the 10-20 PSI range, then that’s a good sign.

You can also do a visual inspection of the filter to see if there are any problems. Look for signs of clogs or leaks, and check that all components are working as they should. Finally, you can also test the water quality with a pool water test kit to see if the filter is properly removing contaminants from the water.

Overall, maintaining your pool filter is an important part of ensuring that your pool water stays clean and healthy. If you’re having issues with the pressure or any other aspect of your filter, be sure to talk to a professional for help.

There are a few different reasons why your pressure might be too high or low, including leaks, clogs, or a broken valve. To check if your filter pressure is working properly, you can look at the pressure gauge and see if it matches what’s actually happening in the filter. If there are any issues with your pool filter or pressure gauge, be sure to consult a professional for help.

Backwashing your pool is a cost-effective way to maintain excellent water quality. The process ensures that your filter gets rid of debris, bacteria, and algae effectively. However, after continued use, your backwash hose dries out and eventually cracks.

Whether it’s your first-time practicing backwashing, or you need help replacing an existing hose, this article is for you. You’ll find a step-by-step guide on installing a pool backwash hose. Read on to discover how to perform this task for DE and sand filters.

How to Connect a Pool Backwash Hose

Step 1: Determine the Ideal Size

Determine the Ideal Size

Before installing a backwash hose, identify the correct size. You can find various sizes in stores, but the most common ones are two inches in diameter and 25, 50, or 100 feet in length.

To measure the length you need, lay the hose flat on the ground from the pipe to the drainage. Afterward, give an allowance of one to two feet. Cut your new hose accordingly with a knife.

Step 2: Remove the Existing Hose

Remove the Existing Hose

If you have an existing hose, loosen the clamp screws with a screwdriver. You don’t have to take off the screws completely to remove the existing hose, but you might need a knife to cut the old one.

Step 3: Clamp the Hose to the Backwash Pipe

Clamp the Hose to the Backwash Pipe

Next, stretch one end of the hose and slide it over the pipe. Insert three inches of the hose into it. Remember, this step takes some getting used to.

When Should You Not Backwash Your Swimming Pool?

When Should You Not Backwash Your Swimming Pool?

Though backwashing your pool is important and a good idea, there are still a few instances when you should not do it to avoid damaging your pool.

Doing it can also be a waste of water, so it is best to know when to backwash and when not to. If the weather is extremely cold, backwashing can cause your pipes to freeze and that can lead to expensive repairs.

If you live in an area with drought conditions, backwashing can waste a lot of water, so it is best to avoid doing it during those times. You should also avoid backwashing if your pool is already low on water, as this could cause your pump to overheat. Lastly, if you have just added chemicals to your pool, wait at least 24 hours before backwashing to allow the chemicals to circulate properly.


Maintaining a pool is a lot of work, but it is also very rewarding. Seeing your family and friends enjoy themselves in the water is priceless. With the right supplies and a little bit of knowledge, you can keep your pool looking great all season long.

With so many options on the market, there is sure to be a hose that is perfect for your needs. It is important to keep in mind that investing in a good quality backwash hose will save you time and money in the long run, so make sure to have a better understanding of your needs before making a purchase to ensure you get the right hose for the job.

There are various filter types on the market, but they all serve the same purpose: to rid your pool of debris, bacteria, and algae. Because of all the work they do in preventing water-borne diseases, they need help keeping your water quality in tip-top condition.

Backwashing is one of the most convenient and affordable ways to ensure your filter works as it should. After all, what goes in must come out. Once in a while, you have to take out all the tiny contaminants that the filter sucks from your pool.

Once you learn how to backwash like a pro, you won’t always have to dismantle your filter and clean every little crevice. Read on to learn everything you need to know about backwashing a pool filter.

What Does Backwashing Mean?

What Does Backwashing Mean

No matter what filter you use, it’s best to keep it clean to maintain your pool’s water quality through backwashing.

It may sound like a complicated procedure, but it’s not. In reality, it’s a method to thoroughly clean a pool’s filter without having to do it manually. The best part is, it only takes a few minutes of your time.

When you backwash your filter, you reverse the water flow, moving it back toward the waste line. It’s an ideal alternative when cleaning and teardown are not practical solutions.

Why Should You Backwash Your Filter?

Why Should You Backwash Your Filter?

There are various ways to wash the apparatus, but why is backwashing ideal?

As water goes through your diatomaceous earth (D.E.) or sand filter, it leaves behind pollutants like dirt and oil. When your filter gets clogged, it becomes less effective.

Backwashing your pool involves sending water backward through your filter and toward a drain port. This pressure forces the debris out, enabling you to remove it and quickly restore the filter’s functionalities.

Think of your pool’s filter like a vacuum cleaner or a water purifying system. As it performs its cleaning functions, it collects unwanted particles in the process. When it gets full, your pool becomes murky and encourages algae growth. For these reasons, keeping your filter clean is an essential step in maintaining your pool.

Regardless of your pool filter type or brand, backwashing typically works the same way. The procedures may vary, but the results are always worth it.

When Should You Backwash?

When Should You Backwash?

As a general rule, it’s best to backwash your pool weekly or in time with your scheduled maintenance. However, there are other indicators to watch out for, like the ones listed below.

PSI Increase

Pool filters often have a pressure gauge. When you first install yours, take note of that number for benchmarking purposes. As you use your filter, the PSI or pounds per square inch figure will increase. The more contaminants you trap in your machine, the higher your PSI becomes.

Any time your pressure gauge goes 8 to 10 PSI points over your usual level, take it as a sign to backwash your filter. For instance, if your filter usually operates at 10 PSI, and you see it rise to 20 PSI, it’s time for a backwash.

High Water Levels

Some factors increase pool water levels, like heavy rain, underground water leaks, and human error. When water levels get too high, your skimmers can’t suction floating debris, leaving your sanitizer exhausted and your swim less safe.

When your water level goes beyond one-half of your skimmer, it’s best to perform a backwash immediately. If you don’t act fast, you risk overflow, compromised surface circulation, and permanent damage to your pool.

Cloudy Water

Cloudy pool water may indicate various concerns, including a clogged filter, improper chlorine levels, or the start of algae formation. No matter the cause, backwashing your pool can bring back its usual crystal clear appearance.

How Do You Backwash Your Pool Filter?

How Do You Backwash Your Pool Filter?

There are three pool filter types: D.E., sand, and cartridge. However, backwashing is not possible for cartridge filters because they don’t have the valves for the process. This section will discuss how to backwash D.E. and sand filters.

Backwashing D.E. Filters

Before you begin backwashing, you need the following supplies:

What Is Diatomaceous Earth?

D.E. is an organic insecticide made of fossilized skeletons of diatoms — one-celled microalgae found in oceans. Once you add the powder to the filter, it attaches itself to the crevices and clumps into a cakey substance. This material can filter out even the smallest contaminants.

How Much D.E. Powder Should I Use?

The amount of powder you need depends on your filter size, so it’s best to revisit your owner’s manual for this information.

If you can’t find details from your guidebook, you can use one scoop of powder for every ten square feet of a new filter. For backwashing purposes, use 80% of this amount. You always measure D.E. powder in pounds, so use a one-pound D.E. scoop for accuracy.

For instance, it’s best to use five pounds of D.E. powder to clean a new filter. However, for backwashing purposes, you can reduce it to four scoops.

How Do You Clean a D.E. Filter With a Multiport Valve?

When it’s time to backwash your pool, follow the instructions below:

  1. Turn off your pool’s filter.
  2. Connect the backwash hose to the waste port.
  3. Switch the multiport valve to Backwash.
  4. Turn your filter back on and run it for two minutes to reverse the flow of the water.
  5. Turn your filter system off again.
  6. Switch your valve to Rinse, turn your filter on, and run it for a minute.
  7. Again, turn your filter off.
  8. Switch the valve back to Filter.
  9. Add D.E. powder to the filter, and make sure to get the amount just right.
  • Prime your pool pump.
  • Take off the strainer lid.
  • Fill the basket with water and let the water run through it.
  • Turn on your pump.
  • Mix the D.E. powder with water to create a cakey substance.
  • Pour the mixture into the pool skimmer.
  • Run the pump for at least 30 minutes to distribute the solution evenly.

Note: Do not turn the valve handle while your pool filter is running. Doing so can break its rubber gasket, which will cause leakage out of the wrong ports.

How Do You Clean a D.E. Filter With a Push/Pull Valve?

There are minor differences between using a multiport and a push/pull valve. Follow the instructions below when using the latter:

  1. Once you’ve turned off the filter system and connected the hose to the backwash port, open the backwash gate.
  2. Afterward, turn your filter back on and run it for three minutes to let water flow out of the port.
  3. Turn your filter system off again.
  4. Close the push/pull valve.
  5. Add D.E. powder to your filter. Refer to the guide in the multiport valve section.

Backwashing Sand Filters

Can you imagine having to remove sand from your filter and washing it manually? It would be a tedious and potentially messy process. However, when you learn how to backwash sand filters, you won’t have to go through this almost impossible feat.

Cleaning sand filters is much faster than washing a D.E. one. You only need a backwash hose to get started.

How Do You Clean a Sand Filter With a Multiport Valve?

Unlike cleaning D.E. filters, this procedure is a straightforward one.

  1. Connect the backwash hose to the waste port.
  2. Turn off your filter.
  3. Switch the multiport valve to Backwash.
  4. Turn your filter system on again.
  5. Let the water course through the backwash port for one minute or until the water runs clear.
  6. Turn your filter off again.
  7. Switch the valve to Rinse.
  8. Turn your filter back on.
  9. Rinse your valve for about 30 seconds.
  10. Turn off your filter.
  11. Switch the multiport valve to Filter.

Note: Do not turn the valve handle while your pool filter is running. Doing so can break its rubber gasket, which will cause leakage out of the wrong ports.

How Do You Dispose of Backwash Water?

How Do You Dispose of Backwash Water?

If you’re not sure where to put the end of your backwashing hose, you’re not alone. However, releasing dirty water on your yard, street, or a nearby creek is not a good idea — and may be illegal depending on where you live.

Remember, your pool contains chemicals that can harm plants, animals, and groundwater. Backwashing can pull hundreds of gallons of potential pollutants.

If you want to keep your community safe and avoid hefty fines, here are some areas where you can dispose of filter backwash water:

Sanitary Sewers

In most cases, local authorities recommend collecting, containing, and discharging backwash water into sanitary sewers. Note that they are different from storm drains and septic systems.

However, these regulations depend on where you reside. Before pointing your hose toward a vegetated area, it’s best to check your city’s rules first.

Storm Drains

Some cities allow residents to release backwash water into storm drains. However, in most cases, doing so requires a permit and reducing chemical or salt levels. To avoid hefty fines, contact your local water authority first.

Plumbing Cleanouts

If your local regulations allow, dispose of backwash water through your home’s plumbing cleanouts. Again, you might need a permit to do so.

Make Backwashing a Habit

Backwashing your pool is one of the simplest and most affordable ways to keep your pool water crystal clear and your filtration system in peak condition. You only need a few minutes of backwashing per week to achieve your pool goals.

When you learn this skill, you won’t have to keep spending for specialists to do it, saving you a lot of money. Now that you know how to backwash like a pro, include it in your list of pool cleaning habits.

Sometimes, pools can turn a ghastly green shade that nobody wants to swim in. If you haven’t cleaned it for a while, you might even find frogs and tadpoles in the water.

However, having a green pool isn’t a reason to panic. There are ways to clean it fast if you have people coming over in a few days.

Hang tight, read this article, and get ready to transform your pool into the talk of the town — for its refreshing blue tint and pristine waters.

Why Do Pools Get Green?

Why Do Pools Get Green?

Before discussing specifics, it’s essential to understand why pools get green. There’s only one culprit during such circumstances: algae.

If your pool has turned a light green hue, the algae have likely started taking hold of your tiles. However, a deeper green shade signifies a more serious infestation.

These conditions are ideal for algae growth:

  • Temperature changes: Algae thrive in warm, humid conditions. They love hotter temperatures of at least 85 degrees. During seasonal transitions, like from spring to summer, it’s best to be extra diligent about cleaning your pool.
  • Improper pH balance: A pool’s pH level is critical for the structure and the people using it. A low pH in a pool can cause damage to your equipment, but high pH content will not kill algae. Finding the right pH intensity can help you keep your pool looking and feeling safe.
  • Clogged filter: When your filter doesn’t work as it should, you have to work double-time to keep your pool clean. With a clogged filter, you won’t only have to deal with algae but also with breeding bacteria and debris.

No matter the cause of the algae growth, the solution is the same. Read on to discover how to get your pool back in tip-top shape.

How to Clean a Green Pool

How to Clean a Green Pool

So, are you ready to turn a green pool blue fast? Follow this step-by-step guide to achieve your pool goals.

Step 1: Test the Water for pH and Alkalinity Levels

You can either use test strips or a liquid test kit to check your pool’s pH and alkalinity levels. Take note of the results, as you’ll need them again later.

You can also list the chlorine levels or other sanitizers. In most cases, when these chemicals go too low, algae will start growing.

Step 2: Vacuum the Pool

Check the pool for visible signs of debris, brush walls, and empty skimmer baskets. Focus on areas with high dirty levels and with little or no circulation.

Naturally, when you start removing the algae and dirt from your pool, you don’t want anything creeping back in. Set your vacuum to waste, clean your pool, and remove as much sediment from the bottom as possible.

Check out our top picks for the best pool vacuum cleaners.

Step 3: Brush Pool Surfaces

When dealing with a green pool, use an algae brush instead of your usual tool. Algae are tough organisms that will stubbornly cling to your pool walls, so choose heavy-duty brush materials over soft nylon ones. Brush the walls, floors, steps, and other surfaces where you might find algae.

Step 4: Apply a Shock Treatment

Pool shocking is the process of adding chlorine chemicals to reach the ideal free chlorine level. Ultimately, the goal is to achieve an amount that will kill contaminants like algae, chloramines, and bacteria without harming the pool or anyone using it.

Even if you often use non-chlorine products to shock your pool, chlorine works best in killing algae. Use products with at least 70% available chlorine for this process. For best results, shock your pool twice.

Step 5: Use Algaecides

The right algaecides can help you treat your pool and prevent future algae growth. Use products particularly designed for green pool algae. When you still see dead algae after treatment, keep brushing surfaces to get rid of them.

Step 6: Activate Your Filter

Before using your filter, clean it according to your manual to remove any build-up. Afterward, turn the filter on and keep it running until the water is crystal clear. Even if you use a pool clarifier to speed up the process, keep your filter on for at least 24 hours to get the dead algae out of the water. Note, you may need to shut your system off and backwash your pool filter a few times during this stage. While backwashing, you can watch the green water come out of the hose. Once it turns clear, you’re good to turn the system off and switch the filter back on.

Step 7: Test the Water Again

When your pool has turned blue again as it should, test the water again. Apart from checking pH and alkalinity levels, inspect the sanitizer intensity as well. Balance everything out so you can start enjoying your pool again.

How Long Does It Take for a Green Pool to Clear Up?

How Long Does It Take for a Green Pool to Clear Up?

Cleaning a green pool can be a fast process, but it requires a lot of work, especially if you have full-on algae bloom on your hands.

In less severe cases, you can clean your pool within one to two days. However, the process might take longer for worse infestations. You will notice improvements in dark green pools within the first 24 hours, but it might take four to five days to free them of algae completely.

Why Is My Pool Still Green After Shocking It?

Why Is My Pool Still Green After Shocking It?

When you find your pool still sporting a green shade after shocking it, don’t worry. It’s not as uncommon as you might think. Below are some of the top reasons why it happens:

  • Metals in the water: When your pool contains metals like copper, it will immediately turn green after a round of shocking. These metals oxidize upon chlorine exposure. The solution is to use metal control products to restore your pool.
  • Copper-based algaecides: Using copper-based algaecides can boost your pool’s metal levels and turn it green. You may also use metal control products for this scenario. In the future, try using metal-free algaecides instead.
  • Unstable cyanuric acid (CYA): CYA protects the chlorine in the pool from the sun’s rays, but high levels can prevent the chemical from killing algae. Keep your CYA level in the 30 – 50 ppm range to prevent it from turning the water green.
  • Phosphate content: This chemical compound provides algae with food. If you want to cut these organisms’ food supply, keep your phosphate levels below 500 parts per billion or ppb.
  • Flocculant use: If you still have problems seeing the bottom of your pool after shocking it, you can use a flocculant to remove the dead algae. It’s fast and effective at removing dead algae, which should clear up your pool.

These techniques should help you achieve a crystal clear pool in no time.

Keeping Your Pool Algae-Free

Keeping Your Pool Algae-Free

Now that you know how to clean your green pool fast, it’s time to learn how to maintain its cleanliness. Here are a few simple steps to achieve such a feat:

  • Check filters and pumps regularly. Stagnant water encourages algae growth, so make sure your cleaning systems work properly.
  • Brush and vacuum once a week. No matter how tedious the process seems, keeping your pool clean prevents algae and other bacteria from thriving in it.
  • Maintain a healthy pH level. Check your pool’s pH and chlorine levels two to three times weekly. Ideally, you should keep it between 7.4 and 7.6 to stave off algae spores before they bloom.
  • Cover your pool. Using a cover keeps out debris and other organisms that might turn your pool green. Additionally, it prevents the sun from supercharging any algae growth.

Final Thoughts

There’s one culprit to your green pool: algae. The good news is, when this happens to you, all is not lost. You don’t even have to drain your pool to get rid of the organisms.

There are ways to clean your green pool fast, including vacuuming and scrubbing surfaces and using treatments. Once you turn the water back to blue, remember to take care of your pool better to prevent algae from growing again.
