17-20k gallons, absolutely crystal clear, still a couple black algae dots under the de-laminated/bulging plaster, but everything brush-able has long been killed.
FC 9
CC 0
PH 7.4 (1 drop to 7.2, 2 drops to 7.0)
TA 60
CYA 50 (rounded up from just under)
CH 200
Old, pitted, some de-laminating plaster pool. High usage, high oil/lotion, high environmental debris, & heavy summer rains coming. Regular MA additions. Totally exposed to central Florida sun.
I have my calcium arriving tomorrow. I know it will not be working any miracles, that's fine. I just want to take better care of this plaster until it is redone in the future.
I plan on dropping PH to 7.2 today before the CH addition tomorrow to minimize clouding.
I was playing with PoolMath and it seemed like pushing my CH up to around 500 gives me a much better cushion to stay closer to 0 in the CSI, especially when PH is at 7.2, which is where I usually drop it to when I add MA.
Also, I pushed my TA down from 120 to 80 during last summer to help reduce the MA additions, and it really worked wonders. Much less MA used and much less PH rise throughout the week. Should I keep TA at 60 or bump back up to 80?
Lastly, this is my first summer ever with this pool having a CYA under 100++ and I'm greatly enjoying being able to test PH without having to dip under the high target FC, which I treat as my minimum FC given the unpredictable rain/bathers, but wondering if I should bump CYA up to 60 from 50 which still lets me test PH without jeopardizing the FC. I've read there is a +/- 15 so that's why I'm asking instead of just doing it.
Thanks for all answers/thoughts.
