Self-Cleaning Fish Tank + Garden Turns Waste to Fertilizer
Ever forget to clean out the tank? Or water the plants, for that matter? This design kills two birds (but no fish!) with one stone, and doubles as a fun instructional tool for kids learning about how natural systems work.
From the makers: “Grow fresh produce right in the comfort of your own home – beans, basil, thyme, baby greens, oregano, mint, parsley, spinach and so many other delicious foods! This closed-loop eco-system uses the fish waste to naturally fertilize the plants above. In turn, the plants clean the water for your pet fish.”
What started as a Kickstarter project (which got more than enough funding) is now in pre-order mode at Back to the Roots. No soil needed – the plants grow on rocks, and are fed nutrients recycled (pumped up) from the fish tank below. That water, in turn, is passed back down, fresh and ready for reuse – essentially an entirely self-contained system (and particularly great for those of us who hate certain regular chores!).
