We upgraded our pump/filter last season to a big Intex sand filter/pump. We are adding the Intex SWG this season and after reviewing threads here I wonder if it's worth digging out the small cartridge pump that came with our pool and setting the SWG on it's own piping loop and timer so it can run longer but at lower flow (and less electricity) than running through the big pump which we only run 3 hours a day or so. I have two poll outlets sitting doing nothing (plugged) so getting water out is a piece of cake and I'm happy to just dump it back in over the edge of the pool.
