Looking for feedback 400gal build

[RamsReef]

Hello,

I'm mocking together a tank, it has gone through many iterations. I think I would like to build a corner one. Stand might be overkill, let me know what you all think.
2x4 legs, 2x6 on top rail.
Plywood tank.

I might make the tank smaller by 4 inch on the backside to allow 6 inchs at back for pipe.

I was going to set overflow at the skinny end and push all water towards skinny end and hopefully suck it out there.

Interesting design. Myself, I'd probably place the overflow in the back left corner. What's in the cabinet/wall to the right of the tank?

I want to push all wast to skinny corner. It's easier to suck out than at the back.

Room beside is a small room that I will be housing fish stuff in and a crawl way under the stairs. The box you see is the area the bifold doors take up.
