Hello; After the tank has sat for long enought to be sure it does not leak you will need to have a plan to set it up in it's final place. I like to shim a metal stand without a tank on it at first, if possible, untill level both side to side and front to back.
I also check the top of a stand with a straight edge for being uniform with no significant bumps or dips. I quite often place a sheet of plywood between the bottom of a tank and the top of a metal stand. I have learned to paint the plywood prior to tank setup from experience. I have read of some using sheets of dense foam board but have not tried this myself.
I shim with metal under the legs of a metal stand and also have learned to protect a floor from the metal legs. If the stand does not have pads of some sort the legs can damage some floors, especially wood floors. On a recent tank setup I put empty cat food cans under the angle iron legs of a metal stand. I also cut thin metal shims from aluminum that would fit inside the cans and a few with a surface area bigger than the can to go under the cans. The thinking is that if I have a small leak it often runs down the leg and will collect in a can and not get onto the floor. I used some rubber furniture pads under a stand that did this for me in the past. I also have been able to wrap a towel around a leg when the leak was slow enough for the water to evaproate away. The rubber furniture pads eventually allow the tank legs to sink into them so I am now trying cat food cans which I think are aluminum.
Back to tank setup. Once a stand is level and true I place the empty tank on it and recheck everything at the top of the tank. If still level I slowly fill the tank and check for level as it is filled. The weight might possibly cause the level to go off as the tank is filled, might need to check the floor structure if this happens.
It may not be practical to remove the 110 tank from the stand as you will need help and a smooth flat place to place it. I often have another sheet of plywood on the place where i plan to place a tank short term just to hopefully avoid putting a glass bottom tank onto a protrusion. At any rate I prefer to move a tank the fewest times possible as leaks can happen from being moved. It may be that leaving the tank on the stand is the safest way to go.
Good luck
