Hello Rocket!
First off thank you SO FREAKING MUCH for posting the plans for building a tank stand. You will literally be saving me hundreds of dollars. For your help with my questions I would be willing to compensate/tip you for your help.
Here is my Build Thread

On that last page you can see the trouble that I ran into with the builder of my stand and basically how I ended up in this awful situation.
On to the help I need.
My tank as it stands is 60" Long 30" Wide and 24" High EuroBraced. My Sump is 55" Long 24" Wide and 18" High
Using your plans - I'm thinking of building the stand using 2X6's with a Center Supports 1/3rd of the way in on Both sides. (I'd rather NOT but this is where the questions come in.)
In Order to fit more equipment inside of the stand I want to build the stand as large as possible with the most usable space inside the stand. To keep material costs down I was thinking of building the following stand Dimensions.
8 Foot Long (I have an area of 8.5 Total Feet or roughly 104") - Planned to use an 8 Foot long because it would take me 3 or 4 Pieces of Ply to Skin it. The back could be 1 sheet of ply with ventilation built in or open. The front can be 1 Piece of Ply with doors cut into the ply around the opening.
I was planning on the following Options
Option A
Build a 8ft Stand using the directions in the original diagram out of 2X6's
Over the area of the stand where the tank will be sitting (center) - Completely reinforce that area with upright 2X4's or 2X6's attached to the bottom Runners (Orange) Put the runners equidistant from the edge of the tank (At the BACK and at the front.) If this works correctly then the sump should be able to fit under the stand itself or the right on a supported sub floor with 1/2" or 3/4" Ply as a base for the sump to sit on.
Option B
Build a stand using the measurements of a 60" X 30 X 38" Cabinet. Then Onto the SIDES of the Cabinet/Original Frame Build ON to the stand using 2x4's to make the 2 side cabinets.
Since my Overflow is centered on the tank and on the back wall away from the edge of the tank does the plans allow me to install my bulkheads and plumbing?
Does the TANK using these plans fit completely FLUSH on the cabinet or is there a Lip? If there is a lip that's FINE. I'm just trying to see if my bulkheads will clear the top back rail to install my plumbing.
