NatalieD,
Where are you moving from, and where to?
That would help us decide if we can even help.
The best way to move a tank is to have a new setup already cycled at the new location.
If you cant afford a whole new display, consider setting up a decent sized tank that would eventually become your sump.
Set it up & let it cycle ( I used old water from water changes of the old tank to start the new ).
Once it has cycled, move all your livestock into that then take your time moving the display.
I would still do it that way even if I hired a tank moving company.
