Cloudy Water
Cloudy pool water is a common problem in swimming
pools. The usual causes are improper filtration, and/or
improperly balanced water. An algae condition or severe
chloramine condition can also cloud pool water.
If a cloudy water condition should occur, check the filter
system for clogs and/or damage and determine if
adequate flow rates exist. In moderate to heavily used
pools a minimum six hour turnover rate is usually
suggested. This means that every six hours the entire
body of pool water has been recirculated through the
filter system. Clogged filters can often be cleared by
backwashing.
After a thorough evaluation of the filter system, the
water balance should be checked. Look for signs of high
calcium hardness, high pH and alkalinity levels.
Filtration
Sand Filters: Check the sand for gaps or hard spots
and/or replace the sand. Generally sand should be
replaced every 3-5 years.
DE Filters: Soak the “fingers” in a filter cleaner. If the
filter is a grid-type filter, hose the grids off and inspect
them for damage.
Cartridge Filter: Replace dirty cartridges with clean ones
and clean the dirty ones for the next replacement.
Consider contacting your service pro for advice before
investigating a suspected filter problem.
