Take the twist out of the noggin! Ensure top is flat.
You can just fix it back to the wall. That's how mine are. No cross braces just one fixing per side at the rear.
I used 3x2 for the legs and front to back (sides)
I think they were 1 1/2x1 3/4 from left to right.
18mm ply on new stuff and 15mm furniture board on old stuff (in vid)
These have held for years.
Both shelves in vid and pics are the same basic design. They work.
Holding 18",24" (left) and 30",36" (right)
(Tanks are now full! In progress shots.)
Right side holds around 510lb water weight.
Shelf from video, modified after move. Add one central leg and span for additional support (T shape) and double shelf thickness.
Held until I built fish house.
5ft x18" x18"
(VERY HEAVY! Approx 270lb slate, 440lb water, plus glass and gravel)
