Angel Lover,
I would not recommend moving a tank containing water as 50 odd gallons weighs over 400lb!! If you are moving 200lb of water in a tank of that size the base could easily break as it is not being supported all the way along like it would be on a stand. If you have a search around for guides on moving fish tanks when you move house these will give some useful guidelines.
Here are a few comments I found on some guides to moving:
Nothing should be moved within the aquarium itself; the twisting stress on seams may cause leakage immediately, or just weaken the seal enough for a later burst.
Before you attempt to move any aquarium it must be emptied of all water, decoration, and gravel. Moving an aquarium with water or substrate would not only be extremely heavy, there is a high risk of damage to the aquarium.
DO NOT UNDER ANY CIRCUMSTANCE ATTEMPT TO MOVE YOUR TANK WITH THE GRAVEL IN IT!!!!!!! YOU WILL BREAK THE SILICON SEAL AROUND THE SIDE AND BOTTOM AND YOUR TANK WILL LEAK, OR YOUR TANK WILL CRACK AND BREAK!!
If you really have to move it with fish in then I would recommend the following:
Switch off all electrical equipment in the tank - especially the heater as it could overheat, or even fall and break. If you can get the heater out without too much trouble it would be worthwhile.
Take out some water into buckets, clean new bins, etc.
Net any fish that you can and put them in the water you have taken out. Assuming that the new stand is going straight in you won't need to worry about a heater or airstone.
Take out as much of the remaining water keeping as much as possible in clean containers. If you can't get all of the fish out then make sure you leave enough to keep them OK - its only going to be for a short while.
Prepare a flat space to put the tank while you swap stands (unless the new stand is not going where the old one currently is). Put down a blanket or cardboard to protect the base from scratching.
Get as many people as you can fit around the tank and CAREFULLY lift it off the stand and place on the blanket/card - you need to keep it level and straight to avoid twisting the tank and breaking the glass.
Swap out the old stand and put in the new.
Get the tank on to the new stand, again being VERY careful not to stress the glass.
Get the water back in - as this will stir up sediment you might want to run your filter for a while to clear the water before putting the fish back in.
HTH, Eddie
