moving Tank Questions

[Jason McK]

I will be moving my 75G and my 40G in the next few weeks. I will have to do it very fast as to not risk loosing coral or fish, but I have come up with a few questions I'm hoping I can get some help with.

Sand bed. There is no way I can move the sand bed without disturbing it. So is it best to kill it and rise it really well, Just put it back and ensure I run the tank until my readings are good and then add my Live stock, Buy New Sand, or go bare bottom?

Coral, Should I pull it all off the rock work and remount it after the move?

I would like to do some house keeping while the tank is down, like deal with some hair algae and a mantis. Will dipping my rock into a fresh water bath to flush the Mantis and then scrubbing the algae off cause the die off to create cycle type levels of Ammonia?

Thanks
