The AquaDom was opened in 2004. It cost about 12.8 million euros. The acrylic cylinder was constructed by the U.S. company. It is now the main attraction of the Berlin Sea Life Centre.
The outside cylinder was manufactured on-site from four pieces; the inside cylinder for the elevator was delivered in one piece. The Aquadom is the largest acrylic cylindrical aquarium in the world, with a diameter of about 11 metres, and it is built on a 9 metre tall foundation. Filled with 1,000,000 litres of water, it contains over 1,500 fish of 50 species. The feeding of the fish and the cleaning of the fish tank is performed daily by 3-4 divers. The fish need 8 kg of fish food.
