A couple thousand pounds of water and rock pressure on the bottom glass should balance out the downward pressure from the edges. That would result in less pressure on the edges.

If you look at the picture I posted above, the foam WAS compressed visibly along the edges. My theory is it compressed as much as it could until it made the bottom so tight it popped.
We just popped a piece of the trim off, and this tank is bottom glass with the sides all on top of the bottom glass.
