Okay and agree, however the point is that 2X4 construction is more than
adequate. Here's a nice DIY link for a stand for 135 gal tank.

take up to 7000 lbs before it snaps!

This is not 100% true. Spruce will take a 7000 psi load that is
parallel to the grain if you keep the wood from bending. The 7000psi
number is for very short pieces of wood. Something like the same
length as width or maybe twice as long as wide. I have long since lost
the link that describes this. If nothing is keeping the wood from
bending the load is much smaller, between 400-600 psi. This is why the
plywood is important. The plywood keeps the frame of the stand from
bending making the stand much stronger.
