A reef aquarium or reef tank is a marine aquarium that prominently displays live corals and other marine invertebrates as well as fish that play a role in maintaining the tropical coral reef environment. A reef aquarium requires appropriately intense lighting, turbulent water movement, and more stable water chemistry than fish-only marine aquaria, and careful consideration is given to which reef animals are appropriate and compatible with each other. ==Components== Reef aquariums consist of a number of components, in addition to the livestock, including: Display tank: The primary tank in which the livestock are kept and shown. Stand: A stand allows for placement of the display tank at eye level and provides space for storage of the accessory components. Sump: An accessory tank in which mechanical equipment is kept. A remote sump allows for a clutter-free display tank. Refugium: An accessory tank dedicated to the cultivation of beneficial macroalgae and microflora/fauna. The refugium and sump are often housed in a single tank with a system of dividers to separate the compartments. Lighting: Several lighting options are available for the reef-keeper and are tailored to the types of coral kept. Canopy: The canopy houses the light fixtures and provides access to the tank for feeding and maintenance. Filtration and water movement: A variety of filtration and water movement strategies are employed in reef aquaria. Bulky equipment is often relegated to the sump. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「reef aquarium」の詳細全文を読む スポンサード リンク
