So I'm about to buy my first hot tub and have been reading up on sanitation. I've been in other peoples hot tub with Bromine and Chlorine, and don't particularly like the smell and feel like a get a lot of skin irritation. So I was told about Spa Marvel and then read up a bit on it.
It sounds good, but some spa dealers have said it cannot be used without an actual sanitizer like chlorine or bromine. It is not approved by health Canada as a sanitizer and by law spas must contain chlorine or bromine.
Another dealer suggested using Spa Marvel and then adding an oxidizer/shock (non Chlorine) weekly is sufficient and I have read many claims proclaiming how well this works.
