Do you guys know how to make one? Im planning on making on and just want to see how some of you guys made yours. I am planning on putting it on a 20g long tank
. Its just my little project. It will be going to a 10g sump. I dont want to drill my tank. I was looking up online and I found the picture bellow. I hope that works because I am seriously thinking about making the same one. http://www.aquariumlife.net/projects/diy-overflow/70.asp
