So I had problems with low pH, I stopped using trichlor, switching BBB method, brought pH up to 7.6, kept chlorine in check and the iron stains come out.
I'm about to follow the AA treatment program, dropping FC to 0, adding AA to get rid of the iron stains leaving my filter on circulate.
My question is: Is it safe to use the pool during this treatment? or is the only risk the increased possibility of an algae bloom because you have low/zero FC?
Other than right after shocking, when it NOT safe to go in the pool?
