Just get a piece of plywood to fit under it. Put it in place. Add a bit of water so you can level it out perfectly. You can always let it sit for a few days like that incase the carpet fibers settle or something... who knows... Then start it up. You will be fine with that size of tank in your house. People have much much larger in similar situations.
