Been using BBB method adding about 6oz after every soak with generally good results.
D1 Amore Bay, 415gal with ozone and UV used about 3 times a week by 2 people.
Leaving town for 2 weeks in a few days and thought Bromine would be better to leave it unattended for that time. Added "SpaLife Bromine Boost" as per package labeling (60grams) then added 10 oz bleach (6.25%) to activate.
Tested with Taylor k-2006 (fas-dpd) adjusted for bromine with no visible bromine detected. Then tested with Aquacheck test strips still nothing!
Thought that maybe the chlorine was being used up to oxidize something in the water before activating so tried 2 tbls of MPS. Had a slight indication on the the test strips then the next morning nothing. Thinking that maybe the MPS was detected not the bromine. Oh ya ran out of DPD powder and not easy to get where I am and have to order it and it takes a few days so I am stuck with strips for now!!
Today added an additional 40gr of SpaLife Bromine Boost and added 10oz of bleach. Just a slight indication, but was gone 5 hours later! I even tried to dilute test sample to rule out bleaching out with no luck. Also tried a small sample size of SpaLife Bromine boost in a large bowl and activated with a drop or two of bleach to test both the strips and the boost. Worked fine!
