How high of an ammonia reading did you have? Was the live rock out of the water long? Is the dry rock mined rock (marco) or was it once love rock, like tonga ect? If it was once live your going to have a cycle still. If you had a decent amount of ammonia expect it to take a few days to a week before you have zero ammonia/nitrite.
I've done several successful same day full tank transfers with Dr.Tims. I did use new sand as well as marco rock so there was no die off/cycle.
