Re:
Hey Derek, I was checking on the softtub canada website and they sell a bromine floater. Curious that the canadian softtub is ok for bromine but the US is not.

I am in Canada. It may be the local dealer, not Softub Canada, who recommends using liquid bromine instead of tabs in a floater, based on problems they may have had here. In the case of my tub, the rain often seeps in around the edges (yes, I know that can be prevented by putting the vinyl cover on!), causing the foam cover to float on the water. I would think that, in that case, the floater would be pressing directly against the cover, and problems could ensue.
