I am getting a hot tub and thought I settled on using Bromine. We have a Chlorine pool. Then I saw how adding Bromine to a Chlorine pool changes the Chlorine to Bromine, which I do not want to do. I am also concerned about any skin issues. My kids will be running from one to another. Should I just use chlorine? I wanted Bromine because Chlorine bothers my asthma, although never in the amounts in our pool, really, only when I use Chlorox for cleaning. We have a salt pool for the chlorine if that matters at all. I wanted Bromine because it works at high temps. The spa will be in the sun, although I though of putting a canopy over it so that may not be a concern for the Bromine.
