What size lumber to hold up a 55g from its corners?
I would like to build a two level stand with a 55g on top.
Because there will be a tank on the bottom, there can't be any middle supports, it will need to be supported from corners. There are some metal stands designed this way.
There will be two cross beams supporting the tank, and a 3/4" piece of MDF for the top that will be affixed to the beams and will add additional support. The rear of the top will likely also be supported from below.
Will two 2x4s be strong enough to avoid sagging, or should I use 2x6? Or possibly three beams of 2x4?
