Gap between tank and stand, need a solution

[smokinreefer]

hmmmm...
I guess part of the problem is that I'm trying to do this while it's in place.

Would have been super easy to put foam underneath when the hired movers were here, except I was told there is no need, as the tank should go directly on the stand that I bought.

Also, since I had to buy the stand for warranty purposes, I believed the metal stand would negate any of these types of problems. Or that they tested the tank and stand out before shipping it to me.

Anyhoo, short of getting a bunch of people together to lift this so I can put foam underneath, any other feasible ideas as to how to correct this problem while the tank sits in place?

or is foam going to be the only solution?
