Hayward - Water Chemistry
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.
