This is a product that's supposed to do away with itchy, smelly chlorine and bromine. http://www.spamarvel.com/index.html" [Broken] "...a unique formulation of natural enzymes, minerals and plant extracts and contains no chlorine, bromine or other harsh chemicals ... made with seaweed, lanolin and other natural compounds as well as Vitamins C and D which contain skin conditioning properties..." It sounds too good to be true. I asked why every pool supply and hot tub outlet isn't selling this product. The response was: "they make their money on chlorine and bromine sales; this would knock out their bread & butter." So how can I determine if this product is a viable alternative to bromine?
