Home > School Of Pool > My Pool Is Cloudy.. What Should I Do?

First, you should find out why your pool went cloudy. It is important to remember that water clarity is 50% chemistry and 50% filtration. (See below for possible causes and ways to improve filter efficiency.) A mid-season water analysis and chemical cleaning of your filter would be the first steps to treating cloudy water. You may also need problem-solver products in addition to chemistry adjustments to restore water clarity. We recommend the following water enhancer products to help.

The first product we usually recommend is Natural Chemistry's Clear & Perfect 8oz ( click to go to product) -- the newest, most improved water clarifier on the market.  Clear & Perfect takes the tiny particles that are causing cloudiness and clumps them together so it is easier for your filter to pull them out. It is important to follow directions and not use too much of this product or else it can actually work against itself.
Additionally, we may recommend Sand Aid (click to go to product). This lightweight powder is added through the skimmer and sits in your filter tightening up the filter media so it can filter even smaller particles than usual. When you use Sand Aid, you will have to backwash very often, as your filter will get clogged much faster than usual.
Finally, if those don't work, we may recommend Floc N Vac (click to go to product). This is a very strong product that attracts particles together and causes them to settle out onto the floor of the pool so that they can easily be vacuumed out. The greater the amount of suspended debris in the water, the faster Floc N Vac will work. However, we do recommend that you vacuum the settled debris "to waste" so that you do not clog your filter. If you use Floc N Vac, your filter should be equipped with a "multiport valve" instead of a push-pull valve or a bump-handle.

Patience and attention to your water chemistry will be the answers for clearing your pool. Prevention will keep it looking clear.
