yep.. assuming you started with dry rock and or shipped live rock..and not locally sourced live rock that is already cycled then once ammonia and nitrites have risen and come back down to zero the "toxic" portion of cycling is over and you should at that point start adding your CUC to do what they do..

If there is any sign of ammonia or nitrite then you are still cycling and need to wait as those are toxic to some level..

Being blunt and having fun
