Contrary to the earlier posts, I've moved multiple times 20+ hours with my tank - to include blizzard conditions - without issue.
This is what I've found useful:
0. Tank is the last thing to come down and first thing to put up.
1. Large cooler. I put my corals and rock inside with a pump and heater, connected to an inverter, connected to the car.
2. Bucket or second cooler. I used this second one for fish, using a pump and heater again. You may need a second vehicle depending on power output or share the heater, moving it between the rock/coral and fish container. I kept fish separate as I was afraid the rocks would shift and squish a fish.
3. Bring all the saltwater you need with you. I used a mix of fresh and used tank water. Take the tank water off the top when tearing it down. Once you start disturbing rocks, a lot of detritus is stirred up and you won't want to transport that water.
4. Bring extra saltwater, just in case. I brought ~130 gallons for my 100 gallon system. Note that this heavy and takes space, but for me I would rather lug around extra saltwater that risk not having enough.
5. If staying overnighting at a hotel, carry the cooler and buck into the room and reconnect the pump and heater.
6. When I got to the final location, only setup the tank. Don't worry about the sump; Messing with plumbing is too much. Just make sure the stand is in its permeant spot, put the tank on-top, fill it with water. You can mess with plumbing the sump in a few days as the house gets in order.
7. Add water and heat. This is the longest part - it'll take hours to reheat the water. Take a nap on the floor while you wait or start unloading the trucks. (I've done both, recommend the nap!)
8. Once up to temp, add back in rocks, corals and fish. You did it! Now work on the rest of the house.
I never had a cycle or die off the three times I've done a long distance move.
This does add stress to the move, but for me, I'm not interested in not having a tank or losing the sense of progress I've had growing a coral from a tiny spec to a giant colony.
Hope his helps somebody.
