I have a AquaRite generator for a 40,000 gal. The pool is roughly 21-22,000 gallons. I have a Intelliflo VS-3050 run by a suntouch and a hayward DE filter. I run the pump at 1200 rpm for 18 hours and 2700 rpm for 4 hours (to boost my cleaner). I have turned my generator down to 30% and I am still getting high chlorine readings. I don't know my flow rate and my next purchase will be a flow meter. My pool builder isn't very familiar with the Intelliflo (prefers 2-speed) or the Suntouch so he is not much help. Are my only options reducing the time on low speed or turning generator percentage down lower. Is there a downside to turning the generator lower? I don't want to turn the rpm on lower speed below 1200 because I don't feel it circulates the water enough. Any help would be appreciated.
