The reason we started using Clear Choice is because I had an allergic reaction to the bromine that we were previously using causing eczema over my entire torso. I decided rather than giving up the hot tub I would research other “non-chemical” solutions. I found your web site, read the testimonials and decided to try it. That was a year ago. We all love it. It doesn’t have the chemical smell, smells more like a fresh river stream! Best of all, no more eczema!
