I am looking at building my 3rd acrylic tank. Everything I have built so far has been 1/2" tanks. I am currently running a 72 X 27 X 24 tank that I built 2 years ago. My question is I want to build a corner tank that will be a triangle. The two back sides will be 36" long and 24" tall while the front will be approx 51" x 24" tall. Can I get by with 3/8" cell cast as long as I brace the top really well? I have always used the guide of 1/2" acrylic up to 24" inches tall but this guide is for rectangular tanks.
