One million litres of Berlin water enhanced with 33 tons of sea salt is circulated every hour in the 25 metres AquaDom at the Radisson Blu Hotel Berlin. With one million litres of seawater, the AquaDom is the world’s largest cylindrical aquarium, a stunning habitat for many species of tropical fish. The AquaDom is maintained by Sea Life Berlin, which is located right next to the hotel. Sea Life Berlin houses 30 freshwater and saltwater tanks, which are home to thousands of sea dwellers.
The highlight of a tour at AquaDom & Sea Life Berlin is the two-story elevator ride through the middle of the AquaDom, during which guests learn about both the tropical fish inhabitants and the architecture of the AquaDom.
The aquarium is habitat to more than 1,500 tropical fish and over 50 different species, including trigger fish, hogfish, humphead wrasse (Cheilinus undulatus), blowfish (Tetraodontidae), surgeonfish (Myripristinae), soldierfish (Tetraodontidae) and swarm fish, like Cero mackerel (Scomberomorus regalis) and Silver moonfish (Monodactylus argenteus).
The two-storey glass elevator inside the AquaDom (5 metres high/weight of 25 tons) has a capacity of 48 people, including one guide.
