Has any one had any success using BBB in a hot tub? I am currently using Baquacil (Yes it sucks...) I used to use Bromine but it would seem to make me break out in a rash every once in awhile. I use the tub a lot. Baquacil has keep the tub rash free for a few years but it is almost always cloudy which kind of give me the creeps...Not to mention the (6) DIFFERENT bottles of crap that I have to stock...

Also, How about salting a hot tub up to 2500PPM? Would that be damaging to the guts of the tub?
