What makes a pool have cloudy water?

Answer 1

• Cloudy water can be caused for a number of reasons: poor filtration, imbalance of chemicals in your pool such as total alkalinity, pH, calcuim hardness and chlorine, imbalance of total chlorine and free chlorine (referred to as chlorine demand), etc.
• It could also be that your have a lot of micro particles that your filter cant catch. You might want to try a chlorifier that makes the tiny particles clump together and easy to remove with a vacuum.
• This condition occurred with me twice last year. The diagnosis for me was "mold". I was using Bacquacil, and the dealer told me to test for mold by pouring 1 gallon of bacquashock directly into the skimmer. If the return subsequently starts blowing white instead of clear water, it's mold. The only recourse was to superclorinate, which of course made a big mess, then vacuum and restart with bacquacil again after pool cleared up.
• The water is cloudy due to poor water chemistry. Most likely a pH problem. Take water into a pool store. Sometimes cloudiness is also due to using a calcium based shock. Such as the brand sock-it
• Double shock your pool with liquid chlorine (12.5%). A double shock is 2L of chlorine for every 10000L of water in your pool. The cloudiness is likely the start of algae. You may also find a clarifier helpful after double shocking to help eliminate the particles that will settle to the bottom of the pool.
• Make sure all of your levels are balanced. then if there is no improvement add a clarifier ONLY if you are using a sand or cartridge filter. it will clog a filter.
• First make sure ALL your levels are good depending on the filter type that is used perform a backwash vacuum. if using a sand filter try some DE in small doses for it will clog the filter let it run through the filters watch your pressures when they get to the point you normally backwash than do so.
• Have a complete water analysis to find the cause for cloudy water.
• I disagree with all the above answers: There are only two main causes for a white cloudy pool #1 is lack of Sanitizer. #2 is lack of filtration due to a poor filter or a clogged pump. I would start with #2 turn your system off make sure there are no blockages in your pump basket,skimmer & main drain.Make sure your filter is properly cleaned.Then #1 check your sanitizer level make sure it is in a safe operating range. Your pool water should be turned over every 6-8 hours.
• Cloudy pool water is usually the result of one or more of the following: filter/ filtration problems, high calcium hardness level, high conditioner level, high pH, low pH, high total alkalinity, high level of total dissolved solids, low chlorine level, algae, large volume of microscopic particles in the pool water.

Answer 3

Lack of filtration and or improper chemical levels Improper filtration or bad chemical maintenance.
