Hi. New here, having some trouble with my chemistry (low PH, high TA).
I have a 21,000 gallon pebbletec pool. I heat it, min temp is 83 but its now going over that in the daytime as it heats up here in Arizona. So temp is about 85 or 86 now during the day.
My stats are this at the moment:
Total Hardness: 1000 (The water here is exceptionally hard, by the way, out of the tap...)
Total Chlorine: 3
Free Chlorine: 3
PH: 6.8 to 7.0
TA: 110 to 120
CYA: 150
I have read here and other places that aeration is the only way to bring up PH without bringing up TA. But I've been aerating for weeks now with no results. I have a spray fountain attached to one of my returns and I'm running it all day and all night (see picture). But it's not raising the PH.
I've also tried adding borax and soda ash (different experiments) to bring up the PH, but when I do the TA goes sky-high and I have to add muriatic acid to bring it down, which then lowers the PH and I'm back where I started.
I thought I read somewhere that using borax would raise PH with the least effect on TA, and that soda ash would have more effect on TA, but honestly they both seem to spike the TA.
I've been using liquid chlorine recently instead of powdered dichlor with the thought that it might increase the PH, but then I read somewhere else that it has no effect on PH.
Any suggestions?
Thanks,
Stephen
