Cloudy water can be caused by various improperly adjusted parameters. Check the following points:

  • If the pH of your pool water is too high (above 7.8), lower it with pH-.
  • If the free chlorine level of your pool water is lower than 1 ppm, raise it to a maximum of 3 ppm.
  • If the sand in your pool filter hasn’t been cleaned in the last year, clean it with a sand filter cleaner.
  • If all of the above parameters are properly adjusted, add clarifier (sticks or liquid).
