Welcome to our forum.
I spoke to my hot springs dealer and told them, I don't like using bromine and chlorine, they suggested just using the shock (sanitizer and oxidizer) Use one capful (the large cap , that goes on the bottle) once a week to shock and 1 to 3 tablespoons of it after each use. There are only two of us, but occasionally will be 4. Is this ok, it seems great, because I don't get that odor and my eyes burning. I have a ozonator on the tub. All comments appreciated, as always.
"The proof is in the pudding", in this case it's in the water, and you want that to be sparkling clean and crystal clear. Ozone is a powerful sanitizer / oxidizer........
