Hi, pool has been doing well for last two years, but noticed much more pitting and algae in pits. Pictures are on the way. I’ve had this problem before, but not like this. I’ve followed SLAM method, but can’t seem to maintain FC. pH likes to creep up, but goes down with MA. Alkalinity is if and on low, but baking soda raises. When I opened pool in April, it looked good, only two things off were low CYA and CH. Cal Hypo seemed the answer, even though we don’t like pucks, but hard to come by.
FC 0
CC 0.5
pH 7.5
TA 55
CH 250
CYA ~25
Thanks
