This Smart Aquarium Converts Slime Into Food And Maintains The Water Crystal Clear

Probably one of the worst jobs of having a fish tank is to clean the water. Scraping muck and slime from the side of a tank, and continually cloudy water, annoys many fish owners. What if you never needed to do any of these again?

A young designer has created a fish tank that not only cleans itself but also turns slime into food! All that is required is that you top up the water occasionally and feed the fish!

Suzy Shelley created the 15-litre tank with a self cleaning filter which never needs to be replaced. It recycles the bacteria into plant food and keeps the water crystal clear.

The tank, which is called Avo, has a revolving bed which naturally removes ammonia, nitrite and nitrate from the water, ensuring that the water never needs to be changed.

“Harmful ammonia, nitrite and nitrate are naturally removed from the water, meaning the water never needs changing,” according to the company called Noux.

A bright idea: Avo features smart LED lighting that is optimised for plant photosynthesis and growth, which leads to clear water. It glows red in the morning, white during the day, and blue at night to look pretty in a room

Avo features LED lighting for plant photosynthesis and growth, which keeps the water clear.

The lighting is soft red in the morning, white during the day, and blue in the evening.

The tank is designed for tropical fish with a constant water temperature of  27°C (80.6°F).

The heating elements are positioned to create convection currents which help the nutrients reach the roots of plants.

The plants are housed in seven trays so they can be easily maintained and moved around to change the look of the tank.

Shelly says that it has taken her over four years to perfect the tank which is packed with technology to keep the fish, plants and bacteria in harmony.

“I’ve always kept fish and it was a steep learning curve in the early days – trying to maintain a tank properly, making sure my fish were healthy and had a clean tank.”

“Fish keeping isn’t as easy most people think…there’s important bacteria in the tank that need to be maintained, plus there’s the weekly water changes and smelly filter cleaning needed to maintain a healthy tank,” she wrote on Avo’s Kickstarter page.

“I decided I’d design something that takes the stress out of keeping tropical fish and makes fish keeping simple, beautiful and above all enjoyable.”

“Avo is packed full of technology and clever design features that make it really, really easy to keep fish.”
