My relatively new salt/gunite pool is experiencing MAJOR ph drift. I am putting in 2-4 cups of MA per day. I believe the major contributor is the massive amounts of aeration the pool gets from the 4 skuppers on the raised beam wall and the 26' negative edge. My analysis (per Leslie's which coincides with my own) is as follows:
FC: 2
CH: 250
CYA: 30
TA: 80
PH: 8.0 (but has been brought down to 7.4 since test)
My TA seems to hover in the 70-80 range, but the PH is a constant issue. I'm trying to stay on top of it rather than letting it get too high and then adding gallon plus to bring it back down. I typically add MA when the skuppers are on, as to circulate it more quickly. Also, the skuppers don't run through the filter/heater, so I figure there's less chance of damage going that route. Obviously, it adds to the aeration factor though, which I guess keeps my TA so low.
Please help me figure out what I can do to get my PH in check. Is this to be expected or a result of new plaster (Diamond Brite)?
Thanks!
