NOTHING LIKE OLD SCHOOL: The Clear-Free Premium Under Gravel Filter is air driven and utilizes an Air Pump (not included) to cycle crystal clear water throughout your aquarium, while keeping a crisp and neat look inside. This means there’s less “moving parts,” making for simplistic and easy maintenance. This filter is suitable for most 10 gallon aquariums.

BIOLOGICAL, CHEMICAL, AND PHYSICAL FILTRATION: As air is pushed through the Air Stones and rises through the Lift Tubes, water is gently suctioned through gravel and the filter plates, allowing both air and water to pass through the Filt-a-Carb Activated Carbon Cartridges. When water continues to be drawn through, anaerobic bacteria collects and colonizes within the gravel and filter plates.

ALSO AERATES YOUR TANK: Since the Clear-Free Premium Under Gravel Filter is air driven through the use of Air Stones and an Air Pump (not included), it also aerates your tank. In essence, your aquarium is being filtered and aerated at the same time, though the same system! It’s a filter and bubbler in 1!

SHOWCASE THOSE BEAUTIFUL COLORS: While keeping your Bettas safely separated, the double-sided dividers are both opaque and see-though! If you wish to keep your fish from seeing one another, keep both sides of each wall down. If you wish to see some vibrant displays and flares from your Bettas, lift and remove the colored side of each partition.

UNIQUE FEATURES: The Deluxe Triple Betta Tank also features an under-gravel filter that utilizes an activated carbon cartridge that can be mounted to either side.
