I have an inground pool that is 110,000 gallons and is ran by 2 Pentair VS pool pumps that run 24 hours a day 7 days a week. The PH is automatically controlled to keep the water at 7.4, My issue is I am constantly getting yellow algae on the walls even when my numbers are good. Any ideas why I get algae every week.
