Underwater Waterfall in my 250 Gal Tank

This ENTIRE background is made from scratch by me and my partner @pawsdog. All hand made. The background is made from foam and cement. The waterfall if you are all interested in how he did it be sure to comment and take some guesses on how its done and I will do another video or a step by step on how its done! :) Hope you enjoy our 250 gallon community tank!
