I recently purchased a house that came along with an above ground spa, which includes an ozonator. I've never owned a spa before, so I did a bunch of research on TFP, did a thorough decon with ahh-some, balanced the water according to the forum stickies that are always referenced, and then finally added my bromide and did an initial shock with MPS.
From everything I've read on the forum, it sounds like ozone does oxidize bromide into bromine, but a floater (or regular oxidizer addition) is still necessary. The problem I'm having is that the bromine levels always seem to be fairly high, even with little to no floater usage. When I did the initial MPS shock, I followed the directions on the bottle and ended up with about 19ppm of bromine. I had to leave the cover off and the floater out for like two days to get the level down to 5ppm.
Since then I've added my floater (pentair rainbow lifeguard) back in with the opening almost entirely closed off, and the bromine levels went back up to about 8ppm. So I'm not sure what I need to change in order to keep the bromine levels in the 2-4ppm range. Just leave the floater out entirely? Use the spa more? I already have the filter cycles dialed down to 60min per day, in addition to whatever runtime happens during periodic automatic heating.
Thanks!
