EcoQube C+: self-cleaning aquarium fuels its rooftop herb garden with fish feces

The EcoQube C+ is a successor to the company's earlier aquariums, but uses the same aquaponics filtering system to grow plants and keep the tank clean (no scrubbing or filter replacements required). This approach relies on the symbiotic relationship between fish and plants to produce clear water. When the user feeds the fish, they produce waste that is rich in ammonia. That ammonia is broken down into nitrates by bacteria in the water and filtered through the plant's growing medium, which absorbs the nitrates for fuel. The filtered, ammonia-free water is then returned to the tank. This diagram here shows how it works. The C+ model measures 11.25 in (28.6 cm) wide, 8.25 in (20.9 cm) thick and stands 22.5 in (57.1 cm) tall. It comes with double the tank space of the standard EcoQube C, with a 3 gallon (11.35 L) capacity. Up top, there are now five separate slots for plants, flowers and herbs rather than just one. Other features include a built-in waterfall and overhanging customizable LED light that can be controlled via remote control.
