Pool is looking well. I'm trying to get my TA down to below 80, it's currently at 75 so I'm happy. I've been using muriatic acid to lower the TA then aerating to raise PH. My CSI is too low (-0.63) for my liking, should I be concerned? I'm working on lowering the TA and currently aerating to bring the PH up. I'm looking at keeping the PH at 7.5-7.8. I lowered the TA to reduce PH rising.
I'm aerating to get the PH up to 7.5 or so. I have a SWCG that is the reason for lowering the TA.
TC 5, PH 7.3, TA 75, CH 375, CYA 110, Borates 40, Salt 4000,
With my numbers PH 7.5= -0.49 and PH 7.8=-0.29 Pool is finished in diamond bright.
I realize my CYA is high. I'm working at lowering it slowly. Even at CYA 75 it still would -0.49 and -0.19.
What are your recommendations. Thanks... Currently I'm at PH 7.3
