Not sure how long you will have to move it for, but my wife and I moved the contents our 75 from our living room to our kitchen while laying our new floor down . We took the tank apart at about 10am (I think) and worked until 11pm literally non-stop, no break to eat, drink or anything. The 11pm stop time was when the tank was back in place and filled. I had made water for a few day's prior in some of my Rubbermaids and buckets. And in the rest of the Rubbermaids and buckets went the corals, fish and LR and the tank water with powerheads and heaters going. I emptied the tank down to about the top of the sand and kept the sand. I'm not sure how long it would last the way I did it though. I think much longer than that and it would have been bad. It took a little bit for the tank to recover, but it wasn't too bad. But you might be able to do what I did and just reassemble it in another room for a bit? If you need to borrow any Rubbermaids feel free to PM me. I have a few 38g (I think that how big they are) 1 or 2 18g and a 10g all only used for my fish.
