Tank move and sandbed??

[TheReefGeek]

I would preserve as much tank water as you can, then do a 10 or 15% change right away.

As for the sand, when I moved my tank I did in-between. I rinsed in tank water (this could be your water change!) not very vigorously, just to get the detrius out to avoid release all that detrius at once and spiking the tank. I am sure I lost a lot of life too, but the sand bed came back pretty quickly, and I didn't spike my tank. If you do it this way, if you can get a few cups of sand from an established tank to see with, that would help.
