My pool water is cloudy and I can't clear it up. What could be causing this?
First, check to make sure that the pH is within proper range. If the pH is within range, it could be that you have a dirty filter and it needs to be cleaned. Check to make sure the sanitizer (chlorine) in the pool is in proper range. If it is not, raise the level. Another cause could be the amount of calcium in the water. If too much calcium is present, it can become cloudy. Adding a sequestering agent, on a weekly basis, can prevent this. Lastly, particles too small to be easily filtered out could be causing the cloudiness. A clarifier can be used in order to make these particles filterable.
