So I am looking to build a 80/20 aluminum stand for my tank. I am pretty handy and don't mind doing my research, but I am lost on this one. I have a marineland 150 gal extra deep tank, so it is 48x24. I guess I am confused on where to start, how do I know what size I need for the weight? Also I see some people using corner braces and others not. Can anyone help?
