Hello braintrust, I'm close to opening the pool for the season and my chemistry is nearly perfect except my CSI is lower than I'd like and maybe I need a reality check from someone more experienced. FC - 4.5 pH - 7.7 TA - 60 CH - 275 CYA - 60 Salt - 3000 Borates - 48 Temp - 71° CSI - (-.57)...

Hey TFP, I'm in the process of lowering my TA so that I can add borates (as boric acid) to hopefully slow my pH rise. I've gone through two cycles of adding enough muriatic acid to bring the pH down to ~7.0 and then waiting for aeration via my swcg + spillway to bring the pH back up. I've...

Hey guys, my water parameters are all looking pretty solid except I'm wondering about calcium: FC: 5 CC: 0 pH: 7.6 TA: 70 CH: 300 or 325 depending on how accurate I'm being (I think) CYA: 70 Salt: 3400 CSI: -.32 I was thinking of adding enough calcium chloride to get to 425 because pool math...
