Help.... I am having problems with chemicals in my Bullfrog spa... 552 purchased July 4th 2006... Every time I use it I break out in red blotches on my back and legs, like cigarette burns, weird... all my other family members use it and have no problem... we use the bromine tablets... approx. 3 every 2 weeks, and check ph regularly. Also add once a week water clarifier and scaler remover... Has anyone had any such problems with their skin. Thank you for your replies.
