We put in a new 35,000 gallon plaster lined pool last September. The ph constantly goes up and I use muriatic acid to bring it down. My question, is it normal to have to put in a gallon of acid every second or third day. The ph will go down to about 7.4 and in a few days up to 8.0 or higher. I know that it was going to use acid till the plaster cured, but I think i'm passed that point.
