Bio Media
Kaldnes K1
Developed by Professor Halvard Odergard at Trondheim University of Science and Technology, the Kaldnes Moving Bed™ bio film process has been designed specifically to create the most effective environment for the 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.
Oxygen and food (Ammonia and Nitrites) gives the bacteria the means to grow, whilst the Kaldnes media provides maximum surface area for the bacteria to colonize and produce bio film. It is this process, which removes harmful ammonia and nitrite from the water.
As the Kaldnes media chaotically circulates within the bio tank, it causes old dead bacteria/bio film on the outside to be removed, making space for new younger heavier feeding bacteria/bio films to colonize. Within the wheel is a protected surface which enables colonies of bacteria to naturally follow their life cycle of maturing and dying,and in turn fueling the latter stages of the nitrification conversion process. It also assists in the breakdown of any small particles passing through from the mechanical stage. Therefore, the Kaldnes media maintains both a young bio film and a maturing bio film providing a more consistent filter performance whilst improving water quality, encouraging healthier Koi, and aiding in reducing green water and blanket weed.

Kaldnes K3
Kaldnes K3 media is similar in application to Kaldnes K1 media in that the constant chaotic movement of the air from your pump causes the media to self-clean and thus requires no maintenance. K3 media is different than K1 media as it is designed to be used in the retrofitting of existing filters bays as the slightly larger media size allows for easier configuration and control.
Kaldnes Biochip
Since the development of the Kaldnes Moving Bed process and its successful introduction into the waste water treatment industry in 1991, Kaldnes K1 media has become the industry standard throughout the world. However Kaldnes has not been idle. They have continued their extensive research and development program to further improve the efficiency of their process over the last 12 years.
The BioChip is the result of this program and is much more than simply a different shaped media. Although the total protected surface area is more than 2.4 times higher than K1, this is only part of the story.
The main difference is that the protected area, or quiet zone in the BioChip, is designed to be the perfect environment for micro animals, not just bacteria. The extremely quiet zones created by the hydrophilic layer protecting every cavity in the BioChip is critical to allow these micro animals to flourish. With other types of media, they will be flushed out.
These micro animals feed on small particles such as fish waste, dead bacteria and algae. There are many types of these micro animals as you can see in our close-up photographs. Consider that the Vortecilia (reference fig 1) are filtering 10,000 times their own volume per hour and are feeding on particles up to 5 microns in size! Once fully colonized, the BioChip contains an army of these micro animals, all filtering tens of thousands of times their own volume every hour. The result - gleaming healthy water, high in oxygen content and low BOD will follow.
The BioChip is meant to be fluidized in conjunction with K1 or K3 media, and is an excellent addition to all Nexus filter systems (reference fig 2). Add to existing moving bed systems in ratio of 25% of total media volume.
