In Pool school it says recommended Ph for a plaster pool is 7.5-7.8 and TA 70-90+. But I have read posts saying try to get your PH 7.2.
Our pool is prone to BA so I am wondering if I should lower my PH. My current numbers are:
TC - 15
Also I have heard that BA feeds on phosphate. Should I try a phosphate remover for my pool and if so, which one?
