My TA is 180. My PH also runs high, usually 7.8 - 8. We have very hard water here in AZ, so in the summer, I am dumping a lot of acid in the pool. Probably a gallon or more a week, and that will get me down in the 7.6 range, but it bumps back up pretty quickly. I can control the PH with enough acid, but it never seems to make a dent in the TA reading.
Regardless, the water looks amazing, and I have no scaling in the pool. Eyes don't sting, skin doesn't feel tacky, all other water chemistry maintains easily.
The only side effect from the high TA, is that I have to clean my salt cell weekly.
So, should I be concerned about the TA in this case?
