You can spot treat the remaining BBA with Excel, Hyrogen Peroxide or Metricide 14. The best time to do this is when you do water change where BBA is exposed out of water. Squirt excel directly to BBA and leave for few minutes. Add water back to your tank. In few days you will see BBA will start turn to purple/ red, dying.
