I have been testing my pool daily for almost a month now, have gotten the TA and pH down from very high levels and added substantial calcium (was TA=120, pH>8 and CH=70). Now I have TA about 70 and CH at 350. pH is suddenly stable at 7.7. Water temperature runs 80-85.
But I am concerned that the TA could drop to 60. I switched my fill water from the whole-house filtration system to the direct well water. The former came in at TA=120 and the latter is TA=30. The switch really stabilized my pH rise so now I can run the waterfall without driving pH up above 8. Should I be adding being soda to keep the TA at 70, or increase the CH further to 450 to give me more of a buffer for TA / pH? I am shooting to keep CSI in the -0.2 ish zone, obviously subject to pH and temperature changes.
Overall chemistry:
FC 7.0
pH 7.7
TA 70
CH 350
CYA 70
Salt 3700
Borates 0 (I have boric acid ordered but maybe not needed)
