First, thanks for all the help while I was getting my pool back under control. Life is good and the water is clear. Looking for some guidance or at least a "hey you're headed in the right direction"
I took over pool management in the middle of May. Getting CYA under control required a partial drain/refill and we have high TA in our fill water, so my pool started mid May @ ~160 for TA. By the end of May, I'd gotten that number down to ~80 or so. Since EOM May, the TA has slowly trended downwards to 60. The big rain we got last week finally got the number down to 40. I dumped in the requisite box (55 oz) of washing soda, managed the PH rise with 48 oz of acid over the course of the day and now find myself here:
Build Type: Plaster
Volume: 19000 gallons

Latest Test Result Summary:
FC: 5.0 (11 hours ago)
CC: 0.0 (11 hours ago)
pH: 7.7 (11 hours ago)
TA: 60 (2 days ago)
CH: 280 (3 days ago)
CYA: 40 (3 days ago)
TEMPERATURE: 84° (11 hours ago)
CSI: -0.12 (11 hours ago)
What I find is that every 2-4 days, I'll need to add 24 oz of Muriatic acid to bring pH from 7.9/8 to 7.3. I assume I could do daily acid treatments in smaller doses to regulate pH more closely, but I prefer to handle acid less if I can.
My understanding of the role of TA is rudimentary, but what I read is that TA acts as a sort of buffer for acid demand. I don't notice any swings up or down with pH in my pool - it just seems to rise steadily .2 per day until I squash it down with acid. Is this normal? Should I futz with TA in such a way that I only have to add acid every 5-7 days instead of every 2-3 like now? I hear borates can help? Give me some ideas plz
Thanks!
