Krakens Aquarium now carrying Kaldness media!
What is K1 Media?
Developed by Professor Halvard Odergard, Kaldness Moving Bed Bio film process has been designed specifically to create the most effective environment for nitrification process to take place. The media is engineered in a wheel shape and is slightly positively buoyant, allowing a small amount of water flow (created by adding air to the process) to circulate the media throughout the vessel.
