Hello we have a 30,000 gallon inground vinyl pool and have been having some problems with chemicals and algae. Our pool was really green and we have been treating it for over two weeks now and it's a bit better but still cloudy and chemicals are still calling for 6 gallons of muriatic acid. We have put in a gallon already and our PH is 7.5 but still calling for more. Is this normal? And how can i get this done quickly? We have been running our pool no stop and it's getting very expensive. Thank you.
