I had a pool built it was finished in January and I am figuring out how everything works as I go. I have a purechlor SWG and it seems to be working fine so far. My variable speed pump is set to run on its internal timer for about 8 hours per day. It goes through a few different speeds starting out slow, going faster, and then going slow again. The SWG has a separate mechanical timer but someone advised me that I could just leave the SWG on all the time and let the flow sensor shut off the cell when the pump is not running. Is this an acceptable way to run the SWG? Can I damage the cell this way? I seem to be making the proper amount of chlorine (about 5ppm free chlorine). My lowest pump setting is 750 RPM and the SWG is on during this part of the pump cycle. Any thoughts?
