I just picked up a custom acrylic all-in-one today, and I wanted to show it off. It is an apx. 10g display and 6g fuge/sump. The dimensions are 14x14x20. The guy who built it used 1/2" acrylic, so he didn't need to brace the top. I am going to transfer the rock and livestock from a 10g glass tank that I have set up at work right now. I included some pics, and I will take more once I start to transfer everything over from my 10g.
