I've been having to add at least .5 - .75 gallons of muriatic acid per day for the last few weeks to keep my pH in check. Seems like a lot to me. If I skip a day, my pH goes over 8! +/_ two weeks ago, my TA was 130, now it's 60, and I have not been aerating. I'm guessing that T/A loss is from the incessant muriatic acid -please confirm?
I saw a note on the pool calculator that indicates that with a SWG, a good T/A target is 60-80. But I also know that it's a new pool (1 year old) and that, plus SWG has a tendency to raise pH, thereby needing stabilization -true?
Anyway I'm thinking of adding 5.8 lbs of baking soda to bring the TA up (which will yet again raise my pH, but c'est la vie...) I'm buying muriatic acid by the 5 gallon jug these days.... I'd appreciate thoughts as to a good target level for T/A
Any other thoughts as to why my pH keeps raising so much more dramatically than last summer? -Last summer I had to add muriatic acid maybe once every three weeks, and even then, not a lot -course my T/A was hovering around 110...
pH: 7.6 (at the moment)
CYA: 30 (I know this need to go up to +/- 60)
Any and all help would be appreciated.
