Apr 5, 2024 · Cloudy Pool Water: Causes, Treatment, and Preventive Measures. Cloudy or milky swimming pool water is caused by seven main issues: improper levels of chlorine, imbalanced pH and alkalinity, very high calcium hardness (CH) levels, a faulty or clogged filter, early stages of algae, ammonia, and debris.

- Imbalanced Pool Chemicals. If, like me, you didn’t pay attention in your school chemistry lessons, it could just be a chemical imbalance in the water.
- Circulation & Filtration Issues. Pool water that isn’t being properly circulated is always at risk of becoming cloudy water. That’s because circulation pushes your pool water through your filter system, so without it, the filter can’t work it’s magic and keep your water squeaky clean.

A pool is fighting off bacteria 24 hours a day, 7 days a week, and while the chemicals do the majority of the work, a properly filtered circulating pool helps to ensure that the water and chemicals are mixing properly.
- Chemical Imbalance. One of the more common reasons a pool would be cloudy is a low chlorine level or other chemical imbalance. If there is not enough chlorine present, bacteria is able grow and potentially turn the pool green or cloudy.
- Algae. Algae can cause cloudy pool water. Algae comes in many types and colors, not just green. The first step to treating algae (assuming the chlorine level is adequate) is to identify what color it is.

After adding the baking soda, let at least six hours pass. Your pool water may look even more cloudy for a while. Allow time for the baking soda to dissolve. Test your pool water again between six and 24 hours after you put the baking soda into your pool. You can use test strips or a test kit.
Oct 7, 2017 · For example, if your pool water is too basic, you can add hydrochloric acid or sodium hydrogen sulfate to lower the pH. If the water is too acidic, you can use sodium carbonate to raise the pH. Be sure to also use chlorine stabilizer (aka cyanuric acid) to protect your chlorine levels. 2. Use a pool clarifier.
