Look for advise on how to trouble shoot the following.
Have been noticing white flakes in pool water, like snow flakes and when i cleaned the filter last week, there is a white film on filter pleats, like chalk.
Current water chem is 2.0 for chorine and ph is 7.4 and free chlorine is 110.
There is not build up on salt generator.
Thoughts on how to clear this up?
