Did the OCLT last night....I put in 4 gallons of 10% Chlorine which raised my FC to 10.5 CC was 1 ( thats all I had on me)...in the morning my FC was 4 and CC was 1....I am still draining water to lower CYA....so how much chlorine should I put in? If 4 gallons got me to FC 10.5...does that mean I need 10 gallons to get up to a level of 25ish? My wife is gonna kill me with all these jugs of chlorine I have laying around!
