Aquaponics System Concepts

Aquaponics is an indoor farming system combining aquaculture and hydroponics. Fish are raised in tanks, producing waste that contains ammonia. This waste is filtered by bacteria, converting ammonia to nitrite and then to nitrate, which serves as food for plants. The plants absorb the nitrates, and the clean water is recirculated back to the fish tanks, maintaining a continuous cycle.

What are the main components of an aquaponics system?

• Ammonia

• Nitrite

• Nitrate

Which bacteria convert ammonia into nitrite in an aquaponics system?

• Nitrasonomas

What happens to the clean water after it has been used by the plants?

• It is stored in a reservoir

• It is used for irrigation

• It is recirculated back to the fish tanks

• It is discarded
