Being a nube, I need to know if this is possible or if there is a better solution. I only have a limited (wierd space) amount of space under my 46 gal bow (21.5 x 18 x 10 LxWXD). I am wanting to build it out of glass with a divider across the total length 6 inches from the back. The back division would also be divided in half for small sump (6x10.5) and return (6x10.5). Is this possible? This will give me about a 8-9 gal fuge is that enough? I will try to figure out how to post a diagram. Thanks for the input.
