I have made two attempts to raise my PH and after each addition of Borax, no change. I have been sitting at 7.2. The pool calculator tells me to add 57oz of borax to bring it up to 7.6. I've added roughly 110-115 oz of Borax total with no changes. Is something preventing the PH from coming up? Off the top of my head, my levels are:
FC: 3
PH: 7.2
TA: 90
CYA: 80 (on monday)
CH: 300
