I just read on another forum that TA for vinyl pools is 125-150. I had never heard that before and my pool builder, who only builds vinyls and has been for over 25 years, suggests the standard 80-120. Mine has been holding steady at 110. Should I be adding some baking soda or just leave it alone.
All of my numbers have been perfect, except the pH for which I just added Muriatic acid. Can or will adding acid change the TA?
