Just recently had an fiberglass IG pool installed. Next spring I'm considering installing a SWCG; the question I have is what systems will produce chlorine at low flow rates? I have a variable speed pump (Maxflo VS) and like to run the pump at low speed (1000-1200rpm) for long periods of time as opposed to higher pump speeds for shorter lengths of time. At lower speeds my flow rate is ~20-25 gpm. Any salt systems out there that will produce Cl at that flow rate? Thanks in advance for any suggestions.
