The Marineland Contour Kit features 3-stage hidden filtration with a Rite-Size Z Cartridge and Marineland Bio-Foam, and includes an adjustable flow filter pump. Bright white and blue energy efficient LED lights feature a 3-way switch. The white LEDs create a shimmering light in the water that mimics the underwater effect of sunlight, and the blue LEDs produce a relaxing moonlight glow. The easy-to-assemble kit is beautifully designed and easy to maintain. The tank features curved glass and base with a sleek, sliding glass canopy. Light is hinged for easy access to tank.
