Tank Stand Question

[globe]

My plan is to use concrete blocks as a stand for my 75 gallon. Just wondering if this will support the tank alright in this configuration? I have two press boards on top of the concrete blocks but not sure how much support needs to be in the middle of the tank.

That should be fine, but I would use two 3/4" plywood rather than press board. Plywood has better mositure resistance.
