Or just hide the pink foam with trim.

I'd shim under the top piece of plywood (NOT directly under the tank) to bring the middle part up to support the tank before using foam - one shim every 3"-4" or so.

After the bottom of my 6-footer cracked even with foam underneath it I spoke with a number of woodworkers and a structural engineering friend (albeit in less than sober state ) and base this on their input.

On a GLASS tank you don't need the foam their as long as the perimeter is supported.

Insulation foam won't "squish" down much all at if that's what you're counting on - certainly not 2mm. You'll still probably end up with about a 2mm gap between the foam and the stand if you don't fix the stand itself.

I agree with fkshiu, level the stand like he mentioned under the plywood. I would however use the blue or pink foam also and hide it with trim like mark.
