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

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.

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.

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.
