1st : reservoir filter which consist of components that are stated in the picture above. When the water level is low, the external water supply will flow in; however when water level is high, the pump will work to pump out the water to biofilter.

2nd: the biofilter consist of multiple layers and filter media. So farmer can decide how many layer he wants for his farm. Water will be pump up to the filter.

3rd: the aquaponic is the second filtration, and give extra harvest to the farmer.

4th: the second biofilter is not necessary needed, it depends on the farmer’s need. It can be the same as the first biofilter. However, the water treatment station can replace the second biofilter as well.

5th: the water treatment station consist of UV light( to kill bacteria), Temp sensor ( with heater to control water temperature), DO sensor ( with oxygen supply to control DO level) and pH sensors (to check water pH). So that the water supply to fish tank is in very good condition.

6th: the tank consist of air pump which is a back-up system, auto-feeder, DO sensor and catch net.
