IBC aquaponic systems (IBC means: international bulk container)
One of the most popular aquaponic systems out there. Perfect for back yard or your patio.
The top part is cut off and turned upside down to make grow beds for the plants and the bottom part is used for the fish tank. The grow beds are usually filled with 15-20mm gravel or your preferred grow media.
The water is piped from the fish tank to the grow beds. The grow beds are also used as bio filters that convert fish waste into nutrients for the plants.
In the photos below you will see that we have a constructed a hybrid system that incorporates three techniques, Media beds, DWC (deep water culture) and NFT (nutrient film technique). This IBC aquaponic system was build in a 3m x 4m space
