So between ozone and the more controversial bleach dosing and the less discussed electric current, the conclusion has always been that bromides in marine water inevitably end up as bromate, which is particularly toxic to aquatic organisms. However, perhaps that isn't as big of an issue as we think, assuming we have a sufficient microbiome?

An electrogenic Rhodococcus sp, which is genus of bacteria mentioned above, was isolated from coral reefs. The above paper also briefly brings up how sulfides produced by bacteria also reduce bromate, which is noteworthy but not as directly important as bacterial reducers of bromate. Here is the paper that mentions Rhodococcus electrodipholis: https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.002895
And there's further evidence that denitrifying bacteria can actually reduce bromate together with nitrate, fairly quickly at that: https://www.sciencedirect.com/science/article/pii/S0048969722037913
Given that there is also significant success in regards to electrified reefs, where current inevitably produces bromates, perhaps there is reason to revisit bromate in light of bromate reducers.
