I had been using Baqua Spa chemicals successfully in my hot tub in MD for years. We moved to our beach house in NC two years ago and have not had the same success with Baqua Spa here in this hot tub. I am looking for a suggestion for another type of non-bromine chemical system to use, as I really don't like the smell of bromine/chlorine. I need something that is fairly easy to maintain, as neither my husband nor I are particularly good chemistry students. The hot tub is a 350 gallon Dimension One @home hot tub. Any suggestions would be appreciated.
