How to Treat and Prevent Cloudy Water

Cloudy pools may occur due to a number of reasons. Cloudy water largely occurs because of poor water balance, lack of circulation, poor filtration or the depletion of chlorine/bromine. It can also occur due to dead algae, dirty or old filter sand, excessive debris in the pool or leaving solar blankets on for extended periods of time.

  • 1.

    Bring a pool water sample into Buds for water balance assistance.

  • 2.

    Remove solar blanket from pool and keep it off.

  • 3.

    Adjust pH to 7.2.

  • 4.

    The pool must circulate for 24 hours a day until it is clear. Timers are not recommended when having pool water problems.

  • 5.

    Clean all debris from pump basket and skimmer basket.

  • 6.

    Direct return jets downwards at 45 degree angle in the same direction.

Adjust chlorine to acceptable levels and then choose one of the following options:

  • Option A: Add 50 ml of SPARKLE (for cartridge and sand filter) per 10 000 L of pool water. Walk along the poolside staying mainly in the deep end. Do not use more then the required amount as this chemical may lose efficiency and cause cloudy water. Backwash when the filter pressure rises 8-10 psi or after 48 hours, whichever comes first.

  • Option B: Use Solution 48 Kit as per instructions (Klear Sok must be taken out for cartridge filters).

  • Option C: Add Klear-Sok directly into the skimmer and backwash 48 hours later or when filter pressure rises above normal, only with sand filters.
  • Ensure sanitizing systems are working effectively (i.e. chlorinators/brominators are not clogged; salt chlorinators do not have scale build-up and are generating adequately).

  • As soon as the pool clears, be sure to chemically clean your filter using Filter Cleaner.
  • Filter sand should be changed approximately every 5-7 years, if the filter is being chemically treated on an annual basis.

  • Filtration, circulation, cleaning and chemical balance are extremely important in maintaining a clear and problem free pool. Be sure to test your water on a monthly basis to prevent problems that might shorten your swimming season.

Always ensure pump and filter systems run continuously during all treatments! Every pool should be treated weekly to maintain sparkling, clear water.
