Are DIY tank stands over built?
I am going to build a stand for my 65g tank, but I really don't want a front center support. Its a PIA to work under the tank with that thing in the way.
I did some calcs and got the following:
55 gals water = 460 lbs (assuming substrate take up 10 gal if space)
Substrate = 100 lbs (begin generous since I don't really know)
Assuming a 48 x 14 dimension of the stand and using 2x4s (small width up), that is 217 sq in of surface area just on the 2x4s. Stand will have ply on top of that.
That calcs to around 2.6 lbs per sq in.
The front 2x4 has 84 sq in of surface area, so it will be dealing with about 220 lbs. I can stand on a 2x4 of that length weighing 200 lbs and it doesn't show any deflection at all.
Given these numbers, I don't see a need for a vertical center support on the front of the frame. The legs could be 4x4s which are way more than enough to support the total weight of the tank.
Anyone had experience with a stand built this way?
I have seen one like this, but the top boards were doubled. This required them to be screwed in instead of notched and joined. That to me is a bigger failure point than a single 2x4.
Just seems like overkill, and really heavy to move around.
