Why is the water in my pool or spa cloudy?

Posted by cara knapp on

There are several common causes of cloudy water. Although proper water balance can be an obvious culprit (lack of chlorine, inadequate pH and/or Total Alkalinity levels, low calcium levels to name a few), most cloudy issues stem from poor or improper circulation and/or filtration.

You should always start with adjusting the run-time for your filter when addressing a cloudy condition, and confirm that the filter is clean and operating at optimal capacity and efficiency. In some instances, cloudy water could be the first indicators of a looming algae outbreak; so applying an effective shock treatment could be a good first-step toward corrective action.
