Hi there. I have read several posts multiple times hoping to get educated on owning a pool. I had a 18x33 Swim 'n Play above ground installed on Monday and Tuesday of last week. It took almost 3 days to fill, 15,000 gal. I tested the water and right off had 160ppm alkalinity, 7.6 pH. I read to add Muriatic acid, slowly, aerate, and retest. Over a 48 hr period, I added a gallon of the acid. My alkalinity is still at 140ppm, with a 7.5 pH. My question and concern is do I need to continue adding the acid until I have it down to the 120-100 range?
I appreciate any new information and so far have gotten so much great info from this site. Glad to be a new user.
