I moved my tank with no deaths and no cycle.
I first remover around 2/3 of the water, this way i got a good amount of clear water to put into the tank while it was moved. I put this into coolers. If there are coral, i would move the ones at the top of the tank first, wait an hour, and then take out the water. I then took out all the rock, put it into a cooler, and drained some more water into the cooler with the rocks. ( this water was too murky to use when i got the tank resettled.)
I then took out all the fish and inverts and added them to the buckets of the clean water i took out first. I used new sand when i moved. I had heard from people that when you use the same sand when moving a tank it will create a cycle. So i didnt want to chance it and i had been wanting to change sand anyway. So i guess do what you want at this step. If you do keep the sand make sure that you keep it very moist so there is no die off.
I then moved everything into the new house, first sand, then rock, then slowly added the clean water, then the fish and inverts.
Make sure you have alot of freshly mixed water, your really going to need it. Then just top off the tank. I also bought some bottles nitrifying bacteria just to help with the stress of moving.
Hope this helps, it worked perfect for me!
