Awesome. This will be set up in my 120, and I've been trying to think of ways of getting water flow lower in the tank than I would get from having a vertical spray bar at the top of the water. I figure by adding the air line into the outlets it'll help keep the water oxygenated and hopefully the water flowing in the lower portions of the tank. I'm going to make the outlets look like pipes sticking out of the background, with a larger cave like pipe sitting in the middle. Also trying to make a mario style pipe bubbler.
3D background + filtration plumbing.
