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
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 to 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.
