    Cloudy water

    Cloudy water... Yesterday in the morning when I checked out the pool everything was fine. By midmorning the outside temperature was over 100 degrees and the pool water was cloudy... what happened?

    Hi jamesmillhouse:

    Do you have recent test results you can post? Barring adding calcium, a filter malfunction, or other event that could have dropped dirt/debris into the pool, you may well have some organic contaminant in the pool. Test results would help confirm that. I would also consider running an OCLT.

    A good test kit is an investment, not an expense.

    Cloudy water is usually the first sign of an algae outbreak. To be certain, we need to see you test results. Please post FC, CC, pH, CYA, CH, and TA.
