Changing water and filters becomes a thing of the past with this aquarium, thanks to a floating garden that creates a miniature mostly-closed ecosystem along with the fish living in the tank below. Tank water, which inevitably has a bunch of fish poo in it, gets pumped up to the floating garden, where it passes through a layer of sand containing bacteria that convert the poo into nitrates. Then, the nitrate water flows into the plants, and they absorb the nitrates as fertilizer. Finally, the clean water gets send back into the tank to keep the fish happy.

It’s a very neat and tidy system, and it not only makes your aquarium more interesting, but it makes it easier to manage as well. The design comes from Benjamin Graindorge and Duende Studio, and will be available for purchase early next year.
