270g stand?

[Kenny DePrima]

Hey, just built a stand for my 270g tank. The tank measures 72x36x24. Its rimless with .75” glass. I built the stand using 2x10s for the top brace, 2x4s on the bottom brace, and 2x6s for the vertical braces. Everything is pocket hole screwed. Was wondering if in need to add center braces?

I ran a 6' 180g with no center brace on 2x8s, I dont remeber where the wood beam calculator is that most people use, though others may have it to post.
2 things I would change on your build though...

1) I would add the extra leg attachment boards to give better support (light blue in image below). It really doesnt take much to rip the pocket screws through the endgrain of those legs. Also, if you are not going to skin the stand with plywood, I would add some knee braces (orange below) to help with racking (side to side motion)

2) Glue the boards together rather than just screwing them. A good glue joint will be stronger than the wood that it attaches.

Thanks! I do plan on adding a 2x6 center brace to the back of the stand. I just want an open front.

Beyond adding the center brace, some sort of extra attachment points between the top/bottom boards and the legs is crucial.
That can be the extra boards at the legs or an attached skin, among other methods.
