this is what I've been working on:
shelving for 3'x18" and 30"x13" tanks next to each other
they're anchored into the wall
it was a hellish job because everything is warped - the walls, the floor, the boards I had, and the brackets
and the wall is plaster and lathe with unevenly spaced studs and patches of brick
but now the condos are almost ready for moving in
