Caution
This can kill fish, so err on the side of caution. I would not exceed 5ml/10 gallon. Actually I'd stop way short of that.
I've used H2O2 in a syringe at 1ml at a time to kill BBA. I stopped at 2 spots per day, 2 ml total. The 1/2" area hit would bubble away, and the areas near would die back and be attacked by shrimp. I would hit again several days later, I read in other sources that the effect of H2O2 can be in the tank for 2 or 3 days, so I'd wait that long to insure fish safety.
I read that consistent CO2 is what really does the trick on BBA, though.
