im wanting to build a stand to hold my 90 gallon tank. That part is easy and I was planning on putting a sump underneath that I’m making with a old 75 gallon i was given when I bought the 90 now that I started and was measuring them I realize that they both are 48x18 on bottom. My question is does anyone have a set of plans that will accommodate the tanks without having the sides and platform sticking out since I have to make room for the one on bottom and brace the sides. I will have extra room in back for plumbing so front to back is ok. I have a few ideas but was wandering of a tried and true idea.
