Gap in 55 gallon aquarium?

[therealnickgaga]

I recently bought a 55 gallon aquarium, and just noticed a small gap between one of the glass panels and the black trim around the top and bottom. It appears as though the assembler did not push the pane back far enough, so there is a little bit of an overhang on the glass next to it. Is this bad? The gap is approximately the size of 2 stacked pennies. I am worried that when I get water in there, it will push the glass where it should be and break the seal of silicone.

Thanks!
