Thanks guys. Oddly enough, my QuikChlor manual says nothing about it shutting off at lower temps, but i figured it would since most SWCG's seem to. I guess I let her run and just keep chlorine monitored; I'm definitely going back to bleach when necessary. Right now I'm at the "upper-end" for my SWCG with 2800ppm. The recommended range is 2250-2750.
