This is my DIY in photos of the aluminum stand that was built by my built by my Dad, elder brother, and me for my Marineland 220 Xhigh aquarium.
Part 1 - It's made of 2" square aluminum that it cost about $250. The dimensions are 72.5" x 24" x 24". I drew up the plans with my father's assistance. I did all the prep work. My brother did all the welding. I then ground down all the welds. Then prepared the frame for paint with 0000 steel wool and acetone. I then applied 2 coats of primer and 2 coats of semi-gloss black.
