Hi all,
I've been using the website as a great resource in balancing my hot tub water chemistry but have never posted. I'm using the Brilliance chlorine free bromine system that consists of the sodium bromide startup coupled with a bromine only floater and an oxidizer. My tub also has an ozone generator and UV light sanitizer. I'd been having difficulty keeping my bromine levels up. I'd oxidize after use per chemgeek's recommendations and the levels would shoot up past 10ppm but within a day or two they'd fall back down in the 2-4ppm range and often within 3 days it be at .5ppm using the Taylor bromine fas-dpd kit. I adjusted my floater upward - the Brilliance manual said a level of 2-2.5 was recommended for my size tub (355 gallon) but I'd have it set on 7 or 8 and still the levels wouldn't stay up for more than a few days. I couldn't figure out why but read a few posts regarding depletion of bromine by UV. I begun to think that my UV sanitizer was cannibalizing my bromine levels so I did a little experiment and unplugged the UV sanitation light (which runs 24/7 and has water circulating over it 24/7 by virtue of the recirculation pump). It's been 3 days and my bromine levels have stayed in the 5-6ppm range. I've been ratcheting my floater down from 6 and is now on 2 in hopes of taking my bromine levels down below 4. Thought people might find this useful if they're facing a similar problem
