Yes, its typical for the A-Bacs to get very fast at what they do while the N-Bacs are still way behind building up their number for handling the triple amount of NO2 they have to process as compared to the NH3 the A-Bacs have to do. The funny thing is that despite the A-Bacs getting very fast during phases one and two, they sometimes falter in phase 3 and revert back to having trouble clearing 5ppm of ammonia within 12 hours, even though they were indeed doing that earlier on in the fishless cycle!
