Marineland® Contour Desktop kit is a three gallon glass aquarium kit. This kit features Marineland 3-stage hidden filtration with a Rite-Size™ Z Cartridge and Marineland Bio-Foam® (included in the kit), and include an adjustable flow filter pump. Bright white and blue energy efficient LED lights feature a 3-way switch (toggle between white and blue, off, and blue-only settings). 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. This kit features a sliding canopy for easy feeding and water care dosing. This easy-to-assemble kit is beautifully designed and easy to maintain.
