Cloudy Water
If you have cloudy water, check these areas for possible solutions.
First, check the circulation. Make sure your returns point down and towards the opposite pool wall so that they really stir up the water and don’t just circulate it at the top level. This improves the skimming action.
Check the skimmer and strainer baskets and remove any debris.
Check your filter. You may need to clean it. If the pressure gauge is close to 10 lbs over the recommended pressure, your filter is probably dirty. If you use a sand filter, you may need to change the sand.
Check the water chemistry. A high pH can cause cloudy water. Perform a simple test and adjust the pH as necessary.
