Aquaponics is the combination of aquaculture and hydroponics. Aquaculture is the raising of fish, and hydroponics, the growing of soil less growing plants. Plant and fish grow together in a cohesive system. Different parts of the system help other components sustain homeostasis.
Aquaponics, uses a hydroponic bed that allows crops to grown in a nutrient rich solution. The other tank/aquarium is used for the growing of fish. The two systems exist with each other. As the fish grow, the tank accumulates excrement. The water needs to be changed frequently for the fish to survive. The fish waste provides a food source for the plants, and plants provide a filter for the fish. Microbes and red worms found in the fish water are also beneficial to the process. They convert ammonia from the fish excrement into nitrates. Froom here the nitrates, are then removed and turned the solid into a compost that are suitable for plant food.
Aquaponics can improve upon the growing of plants in water systems. Aquaponics eliminates weeds, and small animal disturbances. Aquaponics uses less water than other systems, and there is no fear over watering or under watering. Toxic run off is eliminated as well from aquaponics. Over fertilization or under fertilization is not an issue as well.
