CLOUDY WATER
Cloudy pool water is an unfortunate, but common problem in swimming
pools. The usual causes of poor water clarity are improper filtration, and/or
improperly balanced water. An algae condition, or severe chloramine
condition can cause cloudy pool water.
If the water is cloudy, the operator should first check the filter system.
If backwashing does not decrease pressure to the normal operational level,
the filter may need cleaning. Clean the cartridge and DE filters according
to the manufacturer’s instructions. Inspect the sand in the sand filter for
clumps or air pockets. Consult your local professional if you are not
familiar with filter maintenance. (Note: never release pool water to any
environmentally sensitive areas.)
After a thorough evaluation of the filter system, the water balance should
be checked. Look for signs of high calcium hardness, pH, TDS, and
alkalinity levels.
