Gap Between Rimless Tank and Stand

[drewhoog]

Hi everyone, new to the reefing community and I just purchased a 20 gallon cube tank. I built a stand for it and noticed that I have some slight gaps between two of the corners. Is this an issue, and if so, how can I fix it?

If it were possible, I would remove the top piece of plywood and replace it with another. Maybe not sand it it?
It looks like maybe you put the top on and sanded it, but maybe a little too heavy in those corners?

go with a A-C grade of plywood?

OR,,, add a second plywood layer on top of the first. Then take some 1/2" thick x whatever the exact thickness of the 2 pieces of plywood and wrap the exposed seems/edges. Miter the corners of course.
