Edgy is precisely the word to describe Fluval EDGE. It"s so out there on so many fronts; it"s cool, trendy, breathtaking, contemporary and stylish. Its striking 3D cube design is refreshingly new and revolutionary. EDGE is an eye-catching showpiece that stands out anywhere you put it. It includes LED lighting, so it makes a spectacular substitute for tabletop lamps. EDGE consists of two main components working in perfect harmony: a clear glass aquarium nestled inside an elegant pedestal. The pedestal appears to be clasping the tank, making the aquarium appear like it is suspended in mid-air. The column houses the filter and the electrical wiring is neatly concealed inside the column. EDGE has a clear glass top that allows a clear and virtually unobstructed aerial view of the interior. The cover is completely sealed, which allows you to fill the aquarium right up to the brim, creating a spectacular effect. Water evaporation is minimal. The unobtrusive pedestal structure and the clear top allow a great all-around view. Instead of a traditional canopy, there is a small cover at the top that houses the lighting. EDGE comes in two sizes 6 and 12 gallons. Both models are ideal for countertops, desks and tabletops. The 6 gallon model includes 21 LED bulbs—18 white and 3 blue bulbs. You can turn on all the lights for full illumination or turn on only the blue bulbs to create a night-time moonlight effect. The LEDs create clear and natural-looking lighting that makes fish and plant colors look strikingly vibrant. EDGE comes with a Fluval Power Filter, which is hidden from view inside the pedestal column. The power filter keeps the aquarium water clean. A quiet pump inside the filter circulates the water. As the water flows through the filter, it flows through mechanical, chemical and biological filtering media, which skims and washes the water clean so that fish and plants can enjoy a clear and healthy environment. All required media is included.
