Well, after years of debate we finally did it and are getting a pool! I’ve been researching on and off for awhile and am leaning towards adding a SWG. We are getting a 24 ft round pool, installer is trying to talk me into the Simple Salt System but I have not read good things about this system. Are there specific SWG for above ground pools or are they the same as in ground? He’s telling me the warranty would be voided if using one for inground pools. I’m wondering if we should try the first season without one and then can add next year if we think it’s a good idea. It won’t be installed until mid July at this point anyways.
