Foam under a SeaStar tank?

The stand top is level but the pink insulation I used was wavy and uneven BUT I thought it would flatten out and conform to the tank bottom but now looking it never really did. You can see in the pic of the foam that the scratches,nicks and dings in the foam did not even flatten out from a 1400lbs of weight.

my seastar custom tank had a 1/4" lip under the edge, so they must be using a bunch of different bottom trims as I have seen a 1/2" raised one also.

I left my foam about 1/2" bigger than the edge of the tank so it wouldn't weaken the part the tank edge sat on. the problem with carpet underlay is it is not even and had hard lumps in it so it can be a very bad thing to have under there if the tank settles it down. I have never seen wavy pink corning foam and being homogenious it should compress evenly, but any foam thatr manages to allow the bottom to be suported has the same risks I guess. I just find it weird as sea star was the ones who told me to use that corning pink.
