Some background: I have a 12 gal JBJ Nanocube I've been sitting on a long time. When they first hit the market there were a lot of returns on them. It was a freebie, and when I got it I gutted it and drilled it for a 1" bulkhead. I've thought about just drilling another hole in the back, but the glass is so thin that I'm concerned about it weakening the panel too much. The hole is pretty much centered on the back panel. I also have several external overflow boxes to work with. And I just figured how to put it all together to make a modified herbie style overflow using only one hole! It'll be a nice project for tonight. Pics to come!
