A Proud Man Shows Off His Elaborate Handmade 20,000 Gallon Reef Tank

In episode 5 of the series Coolest Thing I’ve Ever Made, Bill Wann of Aquarium Engineering shows off his elaborate handmade 20,000 gallon reef tank. The tank is so large that Wann had to design a house around it, and he has to suit up in full scuba gear in order to get in and clean it.

Bill Wann designed this entire 20,000 gallon reef tank himself. From the filters to the pumps, he built everything at home in his shop. The tank is so large, that the only way to clean is jump in with scuba gear. As he describes it “The Coolest Thing I’ve Ever Made”.
