I have been working diligently on getting this pool in shape. I seem to be battling with the PH -- even though the TA is 100, my PH quickly (within 48 hours) rebounds to 8.0+ and the acid demand can be up to a quart every other day or so. my current readings are
TC = 6
CC = 0
PH 8.0+ (seems darker than the 8.0 color mark)
We have a SWG - set at 40% and have it run 4 hours/day - between 4pm and 8pm. we have a waterfall and I know (from reading here) that this will increase the PH, but I tested it this morning after filter had been off for 15 hours. should I attempt to bring TA down to 80? I wanted to add borates this year, but I know that the addition of Borates causes a further increase in PH and acid demand.
Any words of advice?
