I used the
AquaFuge Refugium for my 37 Gallon for a while. It works great but I wish I had built a stand in the back to support the biggest one
25.5" x 4.5" x 12" . Even though this one also hang on, but I wouldn't trust the weight it will put on the backside of the tank. I sold mine recently as I moved on to a bigger tank with Sump in the stand.
The stand I am talking about for AquaFuge can be just like this one... (Forum will format it to little weired shape, but you get the idea

So, it will support the weight.
