The Coralife BioCube has a sleek modern rounded edge design and is the perfect innovative all-inclusive aquarium for all needs! The slim low-profile hood contains vibrant LED lighting that is capable of sustaining and growing healthy, vibrant corals and live plants. It also includes an integrated 24-hour timer which makes it easy to control the three independent light channels for maximum beauty: bright white, sparkling blue and color enhancing LEDs. The automatic 30-minute sunrise/sunset and 60-minute moonrise/moonset function is incorporated to replicate a natural day/Night cycle for your aquatic environment. Coralife LED BioCubes make great starter aquariums because they feature a compact and customizable filtration chamber that is already built-in to the back of the aquarium – easy to setup and maintain. Among other great features are the quiet submersible pump, dual intakes and adjustable return nozzle. Compatible with all existing BioCube accessories. Fish, corals, substrate and décor are sold separately.
