I am a new pool owner. I have a 28,000 gallon concrete pool with a salt system that was plastered a few weeks ago. The salt system has been operating for about a week. In the short time that the pool has been operating, I have not seen a Ph number below 8. I keep adding muriatic acid, but there is no downward movement in the Ph. I understand that newly plastered pools typically have high Ph, but is there anything I can do, or should do, to bring down the Ph? And, if the answer is to add acid, how much and how often. I have been adding anywhere from a couple of pints to a gallon about every other day. Thanks.
