I help a neighbor with apprx 13k gallon vinyl above ground pool following the trouble free pool method with liquid chlorine. Filter is DE, base psi is 12, psi right now is 15. Chlorine level is good according to CYA levels. CYA ~60, FCL 7-9 target, min 5, todays reading was 12 (i like to keep it on the high end). No pool usage this week but have algae on the bottom of the walls to the floor. No bottom drain, only skimmer. Is the algae at the bottom because there is no usage to mix the chlorine at all levels? That is the only thing I can think of. Otherwise it is crystal clear with no abnormal chlorine usage overnight.
