I have excess nutrients and no BBA, that does not explain why BBA is present.Plants also take awhile to start growing after being disturbed. If you ripped out a lot of plants and replanted them you may have had a period where plants were not growing as fast, and hence had excess nutrients.

That would be reasonable.So then why might it be present in his case?
I have a little BBA in my 90 on the opposite end of the CO2 reactor's return. Mainly on the lower portions of some stems that get trimmed often but not that low. I'm guessing CO2 is continually low in that area.
You can dip the plants in a mix of water and hydrogen peroxide/bleach. I have never done this but is you search im sure youll find the ratios. Do you have excel? I have found excellent results just putting some of that in a syringe, dosing directly to the effected area and turning off my filter for an hour. By the next day it is usually red/pink then dies.
