I've been giving this some insight for a school shop project next year. I was thinking about building my own tank and stand. I just don't know how to go about it. Plywood and glass? All glass? All plexiglass? A 2x4 frame with glass or plexiglass windows? How do you guys think it should be done. And is it even cost effective to build my own tank? I've heard unless you're going super big it really doesn't make sense. I was thinking something like 20x20x50. Thanks.
