Water Chemistry is very important
Recommend having the water tested and balance the chemicals after the pool is opened and cleaned.
Pool water should be tested once a month, this provides protection for your equipment.
Adjust salt levels for salt systems only.
keep in mind that chlorine generation only starts after water temperature is higher than 65 F.
Salt systems need a ph of 7.4 to 7.6. If the ph is higher the chlorine generation will slow down and the salt generator cell will get dirty.
If " check cell " light is blinking on Hayward salt system, press and hold diagnostic button for 5 seconds to reset light.
The cell will usually last from 4 to 8 years
