I agree 100%, plus when you can't go to the store and pollen or rain hits and all of a sudden you nice blue pool is dull and green and you can't swim for a week!My main reason for getting a SWG was, after reading up a little bit, I didnt want to keep running to town to buy a lot of chlorine, and keeping adding chlorine every day. It was just waaaaay too much effort and work and driving for me. Had that been my only option, Im not sure I would have gotten a pool. The SWG is doing the work for me. The only maintenance I have to do now is add muriatic acid now and again to level out my pH, and run weekly tests to make sure my SWG is doing its job. Its effortless.
