Is it necessary to lower alkalinity if the ph is okay?

Question

My ph is 7.6 but the alkalinity is 163 in my pool. Do I need to worry about this?

Answer 1

You should. TA is actually more important than pH. It is essentially the governor of all things to do with correct water balance. It is like a shock absorber on a car. At the proper level it  helps reduce the chance of your other readings, from dancing or at least going very far out of range. Right now, with a high TA you have pH lock and also aggressive water. Scale can be an issue as well as calcium hardness.
