@RDspaguy Thanks for the reply. I took a look at the sticky thread. You should be able to drop a bromine floater in a chlorine tub at 1-2ppm and wala - bromine tub! No danger. No draining. Right? (Update: this appears to be the correct answer, when reviewing other threads. Hopefully someone can update "Swim University" and other sources to reflect this).

Ok, sometimes I hate all the conflicting information out there. I just bought a new tub, and am trying to decide chlorine vs bromine. I have a chlorine pool, using liquid chlorine. I read it's very dangerous to mix chlorine and bromine: "mix them together" (sic), whatever "them" is. It is so unsafe, in fact, that you need to completely drain the hot tub AND flush the lines before switching over. God forbid. But then they make dichlor (aka chlorine) shock, which according to the manufacturer and spa depot is 100% compatible with bromine tubs. What is going on here? Who is astoundingly misinformed? They can't both be right: mixing the water is so unsafe you have to completely drain a bromine pool before letting a drop of chlorine touch it, and yet you can shock a bromine tub with chlorine any time. AND my question: is it safe to have a bromine tub and a chlorine pool? You'd obviously be mixing the water going from one to the other...
