BioFishency plug and play system

- improving water quality for better fish growth

The BioFishency Single Pass Biofilter (“SPB”) system is designed to make highly-effective water treatment accessible and appropriate for widespread use in land-based aquaculture. In the plug-and-play, all-in-one water treatment system, the water flows from the top down, removing CO2 and ammonia, and oxygenating the water before being recycled back into the tank.


BioFishency’s cost-effective, all-in-one water treatment system for land-based aquaculture costs a fraction of the cost of high-end water treatment systems and requires minimal infrastructure and expertise. It operates with all different aquaculture methods and enables fish growers to upgrade their existing facilities while using installed infrastructure and working methods.


The BioFishency system enhances water conditions, enabling more feed for increasing fish production with minimal investment.


  • 95% reduction in water use (intensive tanks)
  • 2-5 fold increase in yields (extensive ponds)
  • 2x nitrification (ammonia removal) for improved water quality
  • Relatively low energy consumption
  • Easy to install (plug-and-play installation); no special infrastructure required
  • Small footprint, low maintenance


The proprietary substrate used in the system can be sold as a stand-alone product for a range of water treatment applications.


Test on Danish Trout farm April 2016:

We are testing the BioFishency in a Danish Trout farm where the main problem is too high CO2 levels in the fish tanks.


Goals of the visit and installation are as follow:

  • Short term: To examine the ability of the system to reduce the CO2 concentration in the water – 24-48h trails.
  • Long term: To examine the ability of the system to reduce the TAN levels in the water- 3-4 month trail.
