What is Aquaponics?

Simply put, aquaponics is the cultivation of plants and aquatic animals in a recirculating environment. Aquaponics is a collaboration between plants and fish, and the term was coined from the two words aquaculture (growing fish in a closed environment) and hydroponics (growing plants usually in a soilless environment). It is the co-cultivation of fish and plants in a constructed, recirculating ecosystem using natural bacterial cycles to convert fish waste into plant food. It is an environmentally friendly, natural method of growing food that uses the best features of aquaculture and hydroponics without the need to throw away water or filtrate or add chemical fertilizers.

How BCL Aquaponic works?

Aquaponics combines aquaculture and hydroponics into one production system. Aquaponics relies on fish food to serve as the system’s feedstock. As the fish consume and process this food, they convert it into urine and feces, both rich in ammonia (which can be toxic to plants and fish in sufficient quantities).

The water (now rich in ammonia) then flows out of the fish tank into the biofilter along with the uneaten food and decomposing plants. Then, inside this biofilter, bacteria break everything down into organic nutrient solutions (rich in nitrogen) for growing vegetables.

As we can see, freshwater aquaponics systems rely on 3 main components: freshwater aquatic animals (fish), nitrifying bacteria, and plants – and all three living things depend on each other to survive. Without the bacteria that consume fish waste, even plants would not have a usable form of nutrients – so biological filtration is key. And plant growth removes nutrients from the water, making it clean for the fish.

BCL AquaPonic

A mixture of bacteria designed to process organic waste in aquaponic farm biofilters. In the first stage, the product forms a suitable biofilm in the biofilter on which the nitrifying bacteria can then settle and multiply. The biofilter inoculated in this way gets off to a fast start and at the same time ensures the correct functioning of the nitrification process necessary for the functioning of these systems.


  • rapid start of the nitrification process,
  • ensuring proper treatment of waste in the system
  • protection of fish and plants

Product safety

The microorganisms contained in BCL Aquaponic have all been isolated from the natural environment. They have not been genetically modified in any way. These microbial strains have been classified as harmless to humans, animals and plants. The product has been verified by the State Institute of Health in Prague.
