I have a 48k gallon pool in Central California. The chlorine demand can be high during the hot (100+) summer months. I am considering converting to salt. My ROI could be around 2 years based on buying both 3" tablets and granular chlorine. I have read suggestions that a SWG system should be able to handle twice your pool volume so it does not have to run full time. Looking at the RJ60 but not sure if it will keep up during the summer. So I got the idea of running 2 SWG in parallel? Any thoughts or other suggestions?
