Hey Alex, The first thing to do is... Hey everybody, I moving a tank. free beer for those that help.
Then I would say when do you need the help.
But really, where are you moving it from and too?
How deep is the sandbed? A good rinse would be Ok if it not too deep.
Then borrow lots of buckets and move the live rock in the water you want to keep.
Also is there any livestock or corals that need to be dealt with?
Hopes this helps.
