Here are some pics of the horizontal screen on my QT/pod breeding 10G tank. I know these are not the way to go but I figured I would post some pics of the 3D growth I get on mine bu utilizing the light (13W CFL) in the hood. This screen sets on a through I built to hang of the HOB filter. Very crud but it gets results and the best part is that it was just scrap I had laying around after a couple other projects. So be sides 15 minutes of my time it was free.
