Thanks Tony....that does help. How long do you run your SWCG each day? It seems that mine is way too eager to please and my chlorine level is up at 6ppm after running the pump/filter/Kreepy thing for about 6-8 hours each day.

I know I can adjust it downward and I do....but we just had a horrifying experience with yellow algae and now I'm nervous that the alien algae will return.
