I've had a serious case of BBA for about 6 months and am currently on day 6 of the excel treatment. Just like the other folks mentioned, most of the bba has turned red and seems to have stopped growing. I'm hoping it dies off. One thing I noticed is that since it's turned red my siamese algae eaters eat the older algae instead of only the new smaller bba. They grab onto it and twist and turn until it rips off.
