I know this is on this site somewhere..it has to be, but I just cannot find it. I just put live rock in my tank a couple days ago and tested late last night for the first time for ammonia and have 0.

Most of the rock (fiji) was still in the box from the flight to the states and still wet, and there are a few extra pieces that I added that have been in a "culturing tank" for a while. Shouldn't I see some ammonia, then high spikes, then drop...how long of straight 0 ammonia before I can at least start adding cleanup crew etc.
Thanks again!
Mike
