This is actually the tank that inspired me to want to start my own tank. In the process of determining everything I'm planning to buy within the next 2 weeks however I've switched to getting a 20G long tank. But regardless...here are the links to the youtube video and the guys website...which is incredible btw. He has a bunch of fantastic DIY upgrades to the tank which make it amazing. He also has the 12G version too.
Those are some pretty sweet tanks!
I applaud your decision to switch to a 20g long though, in my opinion those are the PERFECT tank for a beginner and way more versatile than the Edge.
