After 7 months of exile to Texas, I'm getting ready to buy a house over here. I'll be moving the family in June and when I do, I'll be building a new tank. I want to build a 180g tank (72x24x24). The house we buy has to have the room, but I don't think that will be a problem.
I'm planning the stand now by drawing it on AutoCAD. Here is an exported picture of the frame. I want to know what you guys know about the minimum support needed for this much weight (~1550 lbs). I know you guys have built stands, so has anyone build a 24" wide and successfully supported it with 2x4s?

The frame is designed with 2x4s only. I think the picture is intuitive even though it doesn't include any dimensions. Do you have suggestions and/or links to more information for me?
