Learning how to diagnose what is causing your swimming pool water to become cloudy is the first step prior to learning how to treat your cloudy pool water. The Pool Experts at The Pool Factory have put together the following tutorial to help one diagnose and then remedy the causes for one’s cloudy swimming pool.

Factors That Cause Cloudy Pool Water

Cloudy water can be caused by a number of factors. Some factors include:

  • High ph and alkalinity levels (check levels with Pool Check 3-in-1 Test Kit)
  • Failure to run your filtration system/pool filter system long enough with proper chlorine level
  • A worn/dirty cartridge filter
  • Insufficient backwashing

Constant filtration is a must to prevent your pool water from becoming cloudy (generally rule of thumb is to run your pool filter system for at least 8 hours a day).
