Can i cycle a tank with a grouper

[kurtyboh]

you are right i should have said it would be highly unlikely for the op to be cycled so the op would not be confused but bonesurf's assertion that a tank cannot cycle in a day is not correct.

no. it's true that you can't cycle a tank in a day. i would not consider using cycled/cured live rock from another tank cycling the new tank. i would just consider that swapping out one tank for another.
but truly, creating a bacteria colony enough to sustain livestock, cannot be done in one day, no matter what you do.
