The foam absorbs any minor irregularities in the plywood that can cause stress points on the large surface area on the bottom of the acrylic tank.

The foam doesnt have to be thick, just 1/4" or less.

If you're confidant in your work and dont use cheap plywood that is very rough, you can go without the foam.
