Hello TFPer's
I took over pool service, drained and refilled due to high CYA (thanks pool man!). I'm back on the steady maintenance and numbers (I think) and have a stenner maintaining chlorine levels and am using pinch a penny liquid bleach (10%). Pool plaster is prolly 7ish years in age. My question is how frequently I should expect pH to rise and how often to add acid. It seems with a TA of 90 that my pH of 7.6 goes up to 8 in about 2 days. No fill water or rain has occurred. No water features and no aeration.
Here are my numbers (I've been testing almost daily to understand the numbers and keep a log):
10/1 Reading (added 20oz of acid after reading)
FC - 5
pH - 8
TA - 90
10/2 Reading
FC - 5
pH - 7.6
TA - 90
10/5 Reading (added 20oz of acid after reading)
FC - 5.5
pH - 8
TA - 90
My fill water has a pH of 7 (or maybe lower as I cannot read below that) and a TA of 160, so after the refill in early Sept, I spent a while dumping a bunch of acid to lower TA, then aerating to bring pH back up. I got TA down to 80 and figured that was where it needed to be. So I am just trying to figure out what is 'normal'. If adding 14oz every 2 days in my normal, then ok, but I've read others hardly adding any acid at all on a routine basis. Just need some help in trying to determine what is my balancing point.
And a followup question, if adding 14oz every couple of days is normal (and for those folks who accept this as normal), do people actually get a stenner to do acid automation? That seems like a risky proposition to me, but I thought I'd ask.
Thanks for all of the awesome input!
