Ah ok! That's why it's not coming down. Now you have API ammonia lock yes? I wouldn't normally suggest this but.... Since you are trying to fish in cycle with ammonia in your tap water I'd use it until you can get some prime. I'm 99% sure it only converts the ammonia and leaves it still available for the BB. Keep up the water changes and testing and try and keep it as low as possible.
(I'm sorry if I wasn't reading so many threads I probably wouldn't get my wires crossed and would have suggested this earlier instead of telling you it will keep coming down with water changes.)
