I'm trying to evaluate the effectiveness of my SWG. It's rated at "up to" 1.35 lbs of chlorine gas per day. My unit has four settings; 25%, 50%, 75%, 100% and Boost. Are the max chlorine production claims based on the 100% setting or the Boost setting? My unit was branded as a "Calimar Platinum" but is the same unit as the SGS Chlorinators Wave-40 and probably the Circupool SJ-40.
