Things have been going well with our pool this year. The past two weeks we have had more than 8 inches of rain. Needless to say though I have been keeping the FC up as best I can, today I noticed green on the walls of the pool, but is it possible that it isn’t algae? The water is crystal clear and the water chemistry results were as follows:
FC 7.5
CC 0
TA 70
CH 175
CYA just less than 30, does that make it 20?
pH 7.6
CH used to be 250 but rain I guess lowered it. Pool math says I need to add CaCl and Borax. But if this is algae where is the CC? Pool math said the CSI was -4.0. I don’t understand the relationships.
