I have one, so does my b-inlaw. But when I look at my discharge, it aint clear. It stinks too. I've been using rid-x cause I thought thats what your supposed to use. The guy at the health dept. told me don't use anything, human waste is the best bacteria in the world! I have not used the chlorine tabs yet, but will soon. I suppose I'll have to invest in an aerator/diffuser system next spring to help the lake out.We'll see.
