I have a customer whose pool I've been trying to lower the pH level in by adding the specific acids used to lower the pool pH. However, when I go to do the weekly service after a week, the pH level is always 8.0+. I put it lots of acid but it's always high. Please help me. When I researched it, it said to lower the TA but in order to do that, I need to put in acid and that's what I've been doing.
