Styrofoam under 210g?

[BigRiver]

I am currently in the process of a new 210g reef tank and I was wondering if I should place a 3/4'' styrofoam under this tank? I know it is good for smaller tank but is it OK for larger tank???
Thanks!

It may just end up getting squished so much that it will become like a hard board of wood rather than a cushion like material, or it will crack apart from the weight before it can compact down enough.
