added 3 gals of last night brought TC up to 22.5 CC 1.0 FC 21.5, this AM before the sun hits pool I had TC 11 CC 2.5 FC 8.5. Lost 12.5 PPM before the sun. Only lost 7 PPM all day long during the sun. The increase in CC has me worried. Should I add even more Chlorine? I calculated that I would need 5 gals to hit the breakpoint of 25 ppm with the CC at 2.5 ppm.
