Hello, I’m following the pool math app and it says my TA should be between 70-90. It previously was 80 and then I had to add water and my fill water TA is 190. My current TA is 110. My PH is holding around 7.7 - darker than 7.6 but not as dark as 7.8 or 8. When my TA was 80, my PH was low - 7.0 and sometimes below and I had trouble bringing it up and keeping it up. Should I lower my TA or just carry on since everything seems to be holding?

Relax and carry on. Simply lower your pH to the middle 7s whenever it reaches 8.
When adding high TA fill water you can expect a rise in pH. As summer ends and you are filling less your TA and pH will stabilize.
