EYE & SKIN IRRITATIONS
Eye and skin irritations are another common problem for swimming pool
bathers. In addition to such irritations within the water, nasal irritations
can also be noticed in indoor pool areas with poor ventilation and
excessive levels of combined chlorine, also known as chloramines.
There are two basic causes of eye and skin irritations: improper pH and
high chloramines. The human eye is most comfortable in water with a pH
of about 7.5. Therefore a low pH, below 7.2, or a high pH, above 8.0 can
become quite irritating.
A chloramine problem is caused when combined chlorine levels exceed
0.2 ppm. Though many people incorrectly blame high chlorine for
stinging eye irritations, it is actually the presence of chloramines.
CAUSES High or low pH. Combined Chlorine.
TREATMENT Adjust pH to recommended range
& retest. Shock treat or superchlorinate.
FILTRATION
If your water is cloudy, but is in balance, you may want to check your filter.
Filters are an integral part of having clean, clear water. As the filter
collects materials, the pressure will build. To eliminate the material that
has collected, one must backwash the filter. Follow manufacturer’s
instructions for when and how this is done to assure long filter life.
If you suspect a filter problem, the remedy may be as simple as using a filter
cleaner. Beyond this, the remedy may be more involved.
Sand Filters - check the sand for gaps or hard spots and/or replace the
sand. Generally, sand should be replaced every 4-5 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.
You may wish to contact your local dealer for advice before investigating
a suspected filter problem.
