Sump/fuge for a large cube

[mr_alberta]

I would 2 two 3' tanks. 1 for fuge, 1 for sump. If you want one to drain into the other though, I would build a stand (that fit under the stand for the display tank of course) for the sumps that would make the two tanks sit one above the other...like stairs kinda thing if you see what I'm saying...
