“Why isn’t my pool crystal clear?”

Cloudy pool water can be caused by many different things. It can be caused by something as simple as bad water chemistry or something a bit more complex like poor water circulation.

Every aspect of water chemistry can cause water to become cloudy, such as too much cyanuric acid, too much calcium, improper pH and low sanitizer. However, if your water chemistry is perfect and your water is still cloudy, there may be an abundance of contaminants in the water caused by poor water circulation and filtration. The easiest way to fix these issues is to contact a professional pool service to chemically test your water to find the root cause of the problem. If it’s a chemistry issue, they may add chemicals to your water to bring it back into balance or they may recommend draining some of the water if your cyanuric acid or calcium is too high.

If your pool's issue is an abundance of contaminants, they may use a pool flocculant to gather up the tiny particles and vacuum them out or recommend a filter cleaning. For cartridge filters, this is as easy as pulling out the cartridge and hosing it down, or you may need a new cartridge altogether. For sand filters, it may be time for a backwash or it may be time for new sand. For DE filters, it may be time to backwash and replace the DE material. Again, hiring a professional pool service to determine the best course of action for your pool is the best response to a cloudy pool.
