Interesting on the LaMotte. I'll see what I can dig up on their site. If there's an inconsistency, I'd like to figure out who is wrong, Taylor or LaMotte. I accept LaMotte as an authority on the subject too. Again, it doesn't make them right (even Newton was wrong on many points), but it tends to make me expect them to be.
I don't think my spa's ozonator can be shut off. There is a simple panel and there is no option on it to control the ozonator. Maybe if I remove one of the panels. I will dig up the manual and check that though. It is true that the ozone should oxidize the bromamines right back to HOBr, although it can't keep up generally (my bromine levels continue to drop on the DPD with it running anyways, so I shock with bleach or KMPS), so you'd think that I'd still have some bromamines, unless all the bromamines are being oxidized back to HOBr, and the loss is going to bromates? Seems like too much to be explained by bromates though, and if that were the case, my meager packet of brom-start (NaBr) would last a few weeks tops.
BTW, I get a substantial drop in bromine daily on the DPD. I find myself adding about a quarter cup of bleach daily. Is this normal?
