I have a SWG pool, with the following attributes to the water:
TC = 4, FC = 3.5, CC < 0.5
CH = 410, TA = 70, CYA = 45
pH = want to sit around 7.8+
Borates = 0
I therefore spend my time adding around 20 fl oz of Muriatic Acid every couple of days to bring the pH from 7.8+ down to 7.5- 7.6.
I am in a hot climate in Houston, and the pool has a waterfall from the Spa to the pool, which aerates the water (raising pH I guess).
A few questions:
1) Should I just let the pH site at the high end at 7.8?
2) Is adding acid that frequently common or indeed advised?
3) I have been thinking of adding Borax to buffer this pH rise - would that be advised or work?
4) Is my TA in a recommened level for all this?
Thanks in advance for any help anyone can provide.
