Moving a Reef Tank

Moving across town. 70g reef, live rock, a few fish and corals. Live sand
bed. I've moved tanks in the past with no live sand and plenty of rock and
re-established them without a noticeable cycling. Just put everything back
in the tank and it was ok. With the sand bed (and all the poisons that lurk
in the lower layers, as I understand it), can I do the same thing or do I
need to find a temporary home for the fish and corals?
