Foam under a SeaStar tank?

[StirCrazy]

one problem with your explanation here.. once the foam touches the glass then there will be less force on the edges and the trim will not be able to sink any farther, so in theory there is no way the foam can push up against the middle of the glass.. also judging by the picture I would say the middle of the glass wasn't even touching the foam. there are to many rough marks and such that would have all been smoothed out by any contact.
