I have a 56 All Glass corner tank, on the same manufacturer's wood cabinet stand. It is on a smooth wood floor. Is it ridiculous (disasterous!) to try to move it a couple of inches by just pushing the stand?
We moved our 125 gallon using car jacks (2 - one on each end of the tank) laid down on their side.
Because of poor planning the tank was too close to the all and there wasn't enough room behind the tank. We drained down 1/3 of the tank because the original plan was to physically push the tank with the help of reefer friends, but my husband came up with the idea of using the car jacks. We put the jacks between the stand - one jack on each corner- and the wall and each person starting turning the jacks evenly. The tank moved so smoothly that the water didn't even rock. We probably didn't even need to remove any of the water after seeing how smoothly the tank moved. We only had to move in about 1-2 feet. The tank is on a hardwood floor but I had a runner down under it and plastic between the runner and the tank stand. The jacks moved everything together smoothly (tank, runner and plastic).
I moved a 125 about 20yards by draining it halfway and using those "moving men" furniture sliding discs. They work great! I use a crowbar and GENTLY pry each corner up and slide one under. Make sure that you get the ones that are big enough. I would suggest the 3" discs. When you push the tank get help and push LOW on the stand. Slowly but surely the tank WILL slide. You could probably do it with ease by doing a water change at the same time as the move to help lighten it up.Good luck
