OK, now I'm ~24 hours after my bleach addition. Free bromine is 18.75 and combined is 1.25, so it's come up ~4 ppm in the last 12 hours. Ideas? Any reason it would drop so much in the first hour but then be more or less stable ever since?

After running overnight (the pump would have came on for a 30 minute filter cycle, and I assume things ran for heat as well). Free bromine = 15 ppm, combined = 1.25. So it dropped by ~1 ppm in the last 9 hours (ozonator would have run with the filter cycle and I had the tab floater in there).

Thanks for your help. Brand new tub. I filled the first time and it behaved like this. I ran jet cleaner and refilled. Same issues. On the first fill the water looked brown/nasty but it cleared up pretty well after the water was balanced and filtered. Tub had been wet tested by the...

OK, it's been an hour since the last test. 13 drops for free bromine (16.25 ppm) and 1 drop for combined (1.25 ppm) so that's ~17.5 ppm after an hour (or about a 30% drop). I don't believe the pump ran in the last hour, so the ozonator didn't run either. Ideas?

OK will do. Shouldn't the ozonator keep converting bromide to bromine? This tub is only a few weeks old and this water has maybe 5 bather hours total on it.

Yes, with the Taylor test kit

James, I added 200 mL of 8.25% bleach to my tub (380 gallons) and waited 10 minutes. With a 10 mL water sample I used 16 drops of titrant (20 ppm free Br?) then added the R0003 reagent. It took 4 drops of titrant to go clear (5 ppm combined bromine?) So what should I take away from this...

I added R0003 after I titrated to the first clear endpoint. It turned pink again, but again a single drop of titrant cleared it. Do I need to add bleach to the tub to have the R0003 test for combined oxidizer work?

Thanks for the suggestion James, but I don't really understand what this would do. If I add bleach then I should see the oxidizer (bromine) jump. What am I missing? Turns out after I saw your post everything seemed to be fine. Bromine was up around 5 ppm. I was leaving for a long weekend so...

Hi all, First post, but I've been a long time lurker. I have a 18000 gallon plaster pool that we built in 2013 and I've been using the BBB method since day 1 to maintain it with absolutely zero issues. I've learned a lot here and I've very grateful. Last week we received a new spa. Based on...
