How do you fix cloudy pool water?

The first step is having your water tested.

Mostly, cloudy water is caused by off-balance water chemistry—mainly low chlorine levels. Even in a salt-sanitized pool, the chlorine level is low or non-existent can and will cause cloudy water. This can be fixed by adding the recommended dose of chlorine or salt to your pool.

Chemistry is fine; now what?

Poor circulation and filtration can be another cause of your cloudy issue. If the chemistry tests are all in range, the next thing to do is to check your circulation system. Clean out the pump and skimmer baskets, and check the pressure gauge on your pool filter. If the pressure reads 8-10 psi higher than its starting point, the filter must be cleaned, backwashed or possibly have the media (sand/glass) replaced inside it.

Still cloudy?

Even when the chemistry is fine, the filter is clean, and circulation is good, sometimes your pool water needs a boost. Bad weather or an increased bather load can throw off the clarity of the water. At this point, add a water clarifier. Clarifiers combine tiny particles and form larger particles so your filter system can more easily remove them. After adding the clarifier, run your pump continuously at high speed until your water clears.
