I have had my little 5.5 gallon DIY tank up and running now for three years. How time flies! I am wanting to step up to a slightly larger tank and am thinking either a simple 10G or what I would really like is a 20L. Something simple AIO design much like my 5.5. Since I had an extra 10G sitting around I drew up a fuge' wall and divider the other day at the office in SolidWorks and cut out a couple parts on my CNC router. A MJ900 or 1200 pump fits in the rear and I will work up some sort of drop in media basket for the overflow side. Something for Chemi-pure and Chaeto. A little cover to top it off and cover up the mess and all and all it looks ok so far.
