My pH goes from 7.6 to 7.8 in about 3 days, then on up to 8.0 (if I would let it). I add 40 oz. of muratic acid to return it to 7.6 from 7.8 (30,000 gallon pool).
FC = 4.5 (Hayward SWG)
CC = 0
CYA = 50
TA = 90
CH = 30
pH = 7.8
Is it normal for this to happen in the summer? Its already 90 F here in Mississippi, with high humidity. I get about 2" of evaporation per week. I know the CH is extremely low, but I have a vinyl liner, and our water here is extremely soft. Is there anything to do to keep from having to add so much acid? The pH lowers as calculated when I add the amount of acid indicated by the Taylor test.
