Ok I will be moving soon said:Have you read the thread about caring for & feeding a blue ribbon eel? It was very informative. I think it was ThreadOTM on RC a few months ago.
How old is the current sandbed? You could rinse it out to clean it up before putting it in the new tank. http://www.melevsreef.com/rinsing_sand.html
If you set up the tank with water from your current tank, and keep all your LR submerged during the move, you should be able to avoid a cycle.
