Elegance and Performance in a Compact Size

  • Dimensions: 23.6" x 15.7" x 15.7"
  • Display Volume: 23.7gals
  • Glass Thickness: 6mm
  • Includes: Aquarium, Filter Sock, Carbon Pellets, Ceramic Rings, Pump

 

The elegant craftmanship of Waterbox Aquariums starts with their use of 91% transmittance, diamond-beveled, ultra-clear low-iron glass which allow you to see your aquarium inhabitants with stunning clarity. Each glass panel is joined at 90 degrees using high-strength, German-made Wacker silicone to provide maximum durability and to ensure tank longevity.

The Waterbox CUBE series employs an All-In-One filtration system, which is perfect for small setups and those not wanting to fuss around with sumps and plumbing. The AIO filter compartment is broken down into three chambers with dual baffling, forcing dirty aquarium water through a filter sock and several types of filtration media (all included!) for purification. Filtered water then flows back into the main display tank via a return nozzle, which is easily adjustable to dial in water agitation to your liking. With the Waterbox CUBE AIO tanks, you don't have to worry about shopping around for an appropriately sized return pump, cutting up foam to make a leveling mat, or deciding on which filtration media to buy-- All necessary components have been provided, giving you the perfect canvas to build the nano tank of your dreams.
