Pentair Legend Algae Growing in Bag


Apr 30, 2019
I need help trying to get algae out of my pool sweep bag. I have a 22,000 gal in-ground pool . CYA 30, Alkalinity 80, FC 5, PH 7.4
CC 0. My pool consistently has high calcium levals because the water in my area is really hard. I have tried a few of the suggestions in this forum but to know avail. Any help would really be appreciated.
