Welcome to our forum.
I know it is unpopular around here, but these could be perfect BaquaSpa applications.
I was on bromine when I got my first rash. The HS dealer thought I might have become allergic or sensitive to the bromine and suggested I switch to chlorine.
Doc also said I might be overly sensitive to the chemicals or the bacteria; but then again, there should be no bacteria in water that's well sanitized.
