WINTERIZING
In areas where sub-freezing temperatures can be expected,
the filter should be drained and/or removed from its operating
location and stored indoors. Remove and clean cartridges.
Reinstall cartridges in filter tank.
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 unfavorable to algae growth
simply by maintaining a chlorine level of at least 1.0 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.
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 1.0 ppm in the pool water
at all times is the most effective way to prevent algae growth in
swimming pools.
PLEASE REALIZE . . .
Pure, clear swimming pool water is a combination of two
factors—adequate filtration and proper water chemistry
balance. One without the other will not give the clean, clear
water you desire.
Your filter system is designed for continuous operation.
However, this is not necessary for most swimming pools. You
can determine your filter operation schedule based on your
pool size and usage. Be sure to operate your filtration system
long enough each day to obtain at least one complete turnover
of your pool water.
To properly sanitize your pool, maintain a free chlorine level of
1 to 3 ppm and a pH range of 7.2 and 7.6. Insufficient chlorine
or an out of balance pH level will permit algae and bacteria to
grow in your pool and make it difficult for your filter to properly
clean the pool water.
