All kits feature Marineland 3-stage hidden filtration with a Rite-SizeTM 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. The kits feature either a hinged or sliding glass canopy for easy feeding and water care dosing. These easy-to-assemble kits are beautifully designed and easy to maintain.
