Cloudy Swimming Pool Water

The pool water was fine for the first couple of week that the pool was open this summer. But then the bottom of the pool started to turn green. I cleaned the pool and added the correct chemicals. The chemical balance when tested says all the chemicals are fine but the pool water is now very very cloudy and I do not know what to do to make it clear again since the chemicals are correct. Any suggestions?

Hi Pat. I only have two suggestions that have always worked for me. The biggest cause of water problems is not running the filter enough hours a day. The hotter it gets the longer the filter needs to run. If the water starts to turn the filter needs to run 24/7 until the water clears up. With smaller HP pumps, 24/7 may be the best way to go, even when the water is clear.

I also use vinyl shock treatment every two weeks during the hottest months of summer. If I see the water start to turn, which is seldom, I throw in a bag of shock and let the filter run for a couple of days.
