Aquaponics combines hydroponic techniques with aquaculture through the recirculation of water, efficiently and naturally solving the inconveniences both activities pose when they take place separately.

Aquaponics combines hydroponic techniques with aquaculture through the recirculation of water, efficiently and naturally solving the inconveniences both activities pose when they take place separately.

The secret of aquaponics consists of integrating the two activities in a closed circuit thus allowing for the aerobic cycle of nitrogen to happen spontaneously, as it does in nature.

The water from the fish tanks, contaminated by the ammonia resulting from the decomposition of organic waste, is made to circulate through bio-filters populated by colonies of natural nitrifying bacteria. These bacteria transform the ammonia into nitrates that are then used as organic fertilizers for crops to grow, applying hydroponic techniques.

At the same time that they consume the excess of nitrates dissolved in the water, plants act efficiently as filters, purifying it so it can go back clean to the fish farming tanks. Thus, the water can be reused indefinitely without producing any sort of spillway to the outside. Making it re circle, the use of such a scarce source of life as water is tiny if we compare it with that of traditional farming techniques. It is only necessary to replace the losses produced by evaporation which is between 2% and 5% of the total
