Hi all. I'm having an issue with the TA and Ph in my pool. I've been trying to keep my TA around 100 by adding baking soda. I'll put in 8-10 lbs of it, to bring the TA up to 100. It seems to last about a month, gradually dropping to 60. Then I'll throw in some more baking soda, and start the process again. I also end up adding a gallon of muriatic acid every 5-7 days. Is this excessive? Should I just let the TA stay at about 60?
Here are my current readings:
By the way, I put in 2 gallons of acid on Nov 1, which lowered the Ph from 7.9 to 6.8 (I had been out of town for over a week, and things got out of whack). My TA went from 90 to 60 after adding the acid. Checking 4 days later, my Ph rose to 7.3. This kind of movement seems excessive to me. Ideas, anyone?
