I'm thinking of trying to run bromine sanitizer using my SmarterSpa SWG with 1500ppm NaCl + 50ppm NaBr. I expect that the SWG in this setup will primarily produce chlorine, which will quickly react with bromide ions to produce HOBr, the intended active species. I didn't see any posts describing this setup exactly, and the SmarterSpa manual says that if you want to run a bromine system you should use NaBr for the entire salt profile. That would be expensive and doesn't make sense based on my understanding of how bromine systems work by using a "bromine bank" from NaBr along with chlorine-releasing tablets that activate the bromine. Am I on the right track?
Another related question. Folks talk about how MPS will activate bromide from a bromine bank into HOBr, and will raise free bromine levels significantly. Is there a parallel chloride-to-chlorine activation in SW tubs? I've never checked FC levels after an MPS shock in my NaCl setup, but maybe I should.
We generally use the tub a couple times a week, and I notice that the SWG will cycle several extra times over the following 36hrs (normal baseline is 1-2hrs/day). Once I see its cycle rate come back down, I assume the majority of the organics have been oxidized and it's able to hold a FC level again. So it seems like I could skip adding shock after use as long as the SWG completes this burn-off cycle between uses. Does that sound right?
Thanks!
