ALGAE CONTROL
Algae is a form of plant life which can vary in size from a
few thousandths of an inch to the size of a small tree. Of
the many forms of algae, those most frequently found in
swimming pool water are microscopic in size and green
in color.
Algae readily grows in sunlight and can, under favorable
conditions, quickly overgrow a swimming pool turning it
completely green in just a few hours. On the other hand,
swimming pool water can be kept unfavorable to algae
growth simply by maintaining a chlorine level of at least
0.5 ppm in the water at all times. The chlorine level

should be checked at least once a day using a suitable
test kit.
If an algae condition develops and the pool water
"blooms" green, superchlorination of the pool will be
necessary to clear it. Add unstabilized granular chlorine,
or liquid chlorine.
Follow chemical manufacturer's recommendation for
superchlorination. The algae will quickly become inactive
and can then be removed by the filter. Live algae, on the
other hand, multiplies so fast that the filter cannot keep
up with its growth rate. In an active algae situation, it
may be necessary to regenerate the Perflex filter as
frequently as every 2 to 3 hours.
When correctly used, commercial algaecides are effective
against algae, though algaecides should be used in
conjunction with, and not as a substitute for, regular
chlorination or superchlorination.
Maintaining a chlorine level of at least 0.5 ppm in the pool
water at all times is the most effective way to prevent
algae growth in swimming pools.
