Bill Wann is known for his self-built 20,000-gallon full reef tank, which is the focal point of this living room. The tank is the largest privately owned tank of its kind in North America, and Wann designed it and all of its support systems (pipes, filters, sump pools). He literally built the house around the tank, making sure to include a very elaborate and nearly self-sufficient filtration system.
His background is in the pharmaceutical equipment industry. Rebuilding and refurbishing analytical laboratory instruments and equipment. In his spare time, he has always managed and maintained tanks, most of them large, and getting bigger with every new build. Along the way, he had bought every brand of skimmer and calcium reactor he could find over the years and has always been disappointed by the quality and the lack of performance, which never seemed to match the claims. So he decided to build his own. As word of his tank spread interest in the product he made grew, and he began his second business of custom filtration systems, Aquarium Engineering.
