So don't make fun of my MS paint blueprint. I just wanted to get it in some sort of drawing.
I have come up with this very basic design to construct a tank stand for my 115gal that i am building this weekendish. The blue represents the plywood and the red represents the 2x4. Of course i would use glue and nails for all joints. But im worried about the diagonal physics. I think i need some sort of horizantal bracing. But i need to make sure i have enough room in the back left corner for the plumbing. So with that said. im looking to those experts for some advice. I should add that there will be plywood in front and on the sides. This is just the skeleton part.
