Dr Yahia,

In aquaponcs there are these tanks follow by

Fish Tank then Mechanical Tank then Biofilter then sum Tanks then the water pump from sum tank to plants and then back to fish tank.

In aquaponics there are biological process produce high level of Nitrogen and low am mount of phosphorus as the following:

Note*: In aquaponics( Iron, Potassium and other element not produce and must apply thorough adjustment the pH and EC.

1st stage:Start from fish Tanks( fish water composed high amount of ammonia).

2nd stage( mechanical filter)

(this according to the system you will use if used media bed base you does not need for mechanical filter).

Deep culture and NFT you need Mechanical filter for filtration your system before go the Biofilter.

3rd stage( Biofilter tank)

Nitrification process in aquaponics system provides elements for the plants which eliminates ammonia and nitrite through two types of bacteria of which the first type is composed of Nitrobacter, Nitrospina and Nitrococcus, a group of nitrifying bacteria that oxidize ammonia(NH3 or NH4+) convert into nitrite (NO2-) which is also toxic to fish. The second type of nitrifying bacteria composed of Nitrosomonas and Nitrosococcus that oxidize nitrite converts the nitrite into nitrate (NO3-) .

Finally

The plant beds

In aquaponics, the Nitrate and Phosphorus only produce.

Iron, Potassium must be applied for your system as foliar application or nutrient solution to sum tank in aquaponics system.

I suggest for you to read my paper about aquaponics:

Thanks!!

Dear Yahia,

Please have a look at this useful ResearchGate link.

Good luck

Please have a look at these useful PDF attachments also.

Aquaponics is the integration of recirculating aquaculture and hydroponics in one production system. The Deep Water Culture (DWC) is one of the three common methods of aquaponics being utilized at the present, generally implemented at large-scale operations. This technology provides a detailed explanation of the main components of this method and a step by step guide to construct a Deep Water Culture.
