I just converted my pool to salt last month and I am still getting a handle on operating the system. My pool is only 11500 gal and I have the Circupool RJ30 Plus system, so I have plenty of capacity. I have a VS pool pump, so I have the SWG hooked up to a separate timer and I can run it however I want. Since the run time is really only 1/2 the on time, 2 hrs on then 2 hrs off. I currently have mine set at 35%, running for 12 hrs and this seems to be doing fine for keeping the CL levels correct. My question is, does the long run time create higher PH increases? Would I be better of running it at higher % for less time, like 70% for 6 hrs, or is the amount of PH increase the same for a given amount of CL production?
