So last Sunday the kids were in the pool and everything was fine clean and cool
My FC today was 5 We took the solar cover off today (one week ) to find algae
My CYA was down to 40. Not sure why the algae broke out at an FC of 5?????
So my question
I slammed to 16 with the CYA of 40
Should I wait to raise the CYA after I slam for a few days? Or raise the CYA and raise the slam level?
Why would algae take hold on an FC of 5 the Ph was at 7.2
