benjamin graindorge: floating garden fish tank

french designer benjamin graindorge brings an innovative solution to the daily maintenance constraints of freshwater aquariums with a filtering system that is 100% natural: a cushion of sand + plants that adapts to each and every model. its recycling principle based on hydroponics does away with the chore of regular water changes and proposes a new domestic- scale typology, between the decorative glass vase and the water purifying plant.

floating garden uses two techniques for eliminating nitrate wastes voided by fish:

1/ gravel-bed filtration: tank water moves over a tray where it seeps through a 5cm layer of river-sand. the sand bed traps suspended waste particles and forms a host environment for the aerobic and anaerobic bacteria that transform azote into nitrates.

2/ aquaponics : nitrate-enriched water pours over a layer of plant-life. the substratum of roots extracts the nitrates to sustain plant growth, which means that water returning to the tank is pure. needless to say, the vegetation is adapted to wet environments: e.g. amazon-basin plants or tomatoes rather than cacti.

the combination of these two techniques in a simple easy-to-use product marketed for the general public as of spring 2010 is a significant innovation. it is a little known fact that aquarium fish are up front in the domestic pets market.

aquarium water remains stable: it is clean and the tank needs only minimal upkeep: a sponge wipe over glass faces to remove algae deposits, an occasional top-up to compensate surface evaporation, and of course food for the fish.

prototype available in a limited series of 10, each made to order by rapid prototyping process (3D print models). every product is thus unique in its design. comes with tinted aquarium glass. prices on demand. marketed in general public version in plastic and ceramic as of spring 2010. production: duende studio concept input : anthony van den bossche / duende studio on show from 25 june to 25 july 2009 at forum diffusion, paris
