I found TFP while trying to determine how to set up my SWG system and have found it very helpful.
I am an avid swimmer, but perhaps unconventional. I don't like chemicals and given the option, I would swim in a nice, clean lake or river. However, since that is not practical, I have opted for a SWG, hoping that will minimize the amount of harsh chemicals I need to use. I have a fairly small Intex Ultra-frame pool and have rigged up a rather hokey, but highly effective "swim in place" system. I love being able to "lap swim" in the comfort of my own backyard and hope to eventually find a way to inexpensively make the pool a 3 season situation so I can swim most of the year.
