Sean,

Is the purpose of the chlorine primarily to regenerate bromide ion (Br-) back into hypobromous acid (HOBr) on a continual basis (which is what KMPS would do as well, though KMPS is also useful for oxidizing organics before chlorine does to prevent potentially smelly chloramine formation)? Or is it to also supplement the hypobromous acid for oxidation and disinfection? The "NON-USE" seems to imply that it is for the former, not the latter.
