I was hoping adding 50 ppm borates would help with my pH rise but I didn't see any difference. If it matters, my plaster is 11 months old. Here is the rise I saw over the last two weeks:
8/30: FC 5, pH 7.9 // added 1 gal MA
8/31: FC 6, pH 7.1, TA 60, CH 310, CYA 38, NaCl 1200
9/1: FC 6, pH 7.2
9/2: FC 6, pH 7.4
9/3: // not tested
9/4: // not tested
9/5: FC 2, pH 7.6
9/6: // not tested
9/7: FC 4, pH 7.7
9/8, FC 5, pH 7.7, TA 80, CH 310, CYA 37
9/9: // not tested
9/10: FC 4, pH 7.7
9/11: FC 3, pH 7.8
9/12: FC 4, pH 7.8
9/13: FC 5, pH 7.9
My FC was a little erratic as I was learning how to adjust my pump as the pool is now getting more shade and the days are getting shorter.
I notice that the rate of change from 7.1 was faster than the rise approaching 7.8.
I'd like to do something so that I can go at least 16 days without manually adding MA.
