DIY 90 Gallon Tank Stand- Styrofoam/Cork?

So...I am planning on building my first DIY tank stand for my 90 Gallon aquarium this weekend with the help of my father (he is the woodworker of the family). I have been reading about many people using styrofoam or Cork between the Tank and the plywood (plan to use a 3/4" piece across the top of the stand) to help with any "imperfections". Since my tank is a glass tank, and sits inside its plastic frame, is it safe to lay a sheet of rigid foam/insulation or cork that is 1/2-1"thick? I am worried that the tank will sink into the insulation/cork and cause the glass on the bottom of the tank to withstand pressure it normally would not......can anyone offer some insight for me?.......Thanks!!

It is not necessary to add foam underneath a traditional plastic frame aquarium unless the manufacturer specifically recommends it.

I think it's generally a good idea to use foam or something under the tank, mostly it just avoids imperfections causing stress points.

I don't think using a whole sheet should be an issue, but if you are really concerned about it, you could just cut out the center. -I've done this many times before, but mostly because I want to occasionally look at the bottom of the substrate (even though it's not terribly interesting).

Also, you don't need a piece that thick. I really don't think it will cause any problems, but you could go with a thinner piece if that was easier/cheaper.
