Still remember to give it another week or to gotta give the BB time to grow and mature. When adding your stock go very slowly, one fish every two weeks or so, this will allow your BB time to get used to every addition. Corals have a smaller bioload then fish do so you don't have to wait as long with them. You will notice slight ammonia spike everytime you add a fish. Patience is key in saltwater and if ya don't take your time bad things can happen.
