Thread: Filter does not seem to be filtering

    Filter does not seem to be filtering

    We replaced the Zeobriite in our sand filter. The system has been running for days and the water is still cloudy. We can't see the bottom-12'x25' patio pool. The water test from our pool supply store is all within normal ranges. The filter doesn't seem to be taking anything out of the water.Backwashing doesn't seem too dirty. Lots of pressure through the returns but appears cloudy. Help!

    Welcome to the forum

    Pool store 'normal' water test results are very often not what we might consider 'normal'.

    Most cloudy water issues are water chemistry issues.

    Post a full set of test results and we can get started helping.

    Did you thoroughly backwash the filter after adding the Zeobrite?

    Zeobrite is really dirty at first. Did you backwash and rinse? I always forget the rinsing part!
