I am lowering my TA from 160, target 90, then see how PH holds, will go lower if there is still instability.
But I am dosing daily to keep PH at 7. This is consuming a lot of acid. The PH drifts up to 8.0 or 8.1 or 8.2? It gets high. I have been checking my levels each morning and dosing for the last 5 days. I am down to TA @ 110ppm.
Does the temp of the water matter in keeping pH?
The reason I am caring about my levels is I intend to use the spa from time to time. Maybe warm the pool slightly to go swimming. I see on the pool math how temp can change the CSI. What do I need to know about temp and dosing/levels?
Am I doing things right? bring PH to 7 each day.
Stats from today: FC 4.5, PH 8.1, TA 110, CH 190 CYA 55 water temp is 55-60. I added chlorine to bring FC to 7 and acid to bring PH to 7.
