Incorporating Kaldnes Moving Bed™ Process The Kaldnes Moving Bed™ process, which has been scientifically tried and tested in fish farming and waste water treatment for over 10 years, is now available to fish keepers and is exclusively distributed worldwide by Evolution Aqua. 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 nitrite) give the bacteria the means to grow, while the Kaldnes media provides maximum surface area for the bacteria to colonize and produce bio film.
	It is this process that 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, maturing and dying, 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 while improving water quality, encouraging healthier Koi and aiding in reducing green water and blanket weed. Due to chaotic movement of the Kaldnes K1 media, the process is self-cleaning and requires no maintenance. This allows the filter to reach optimum effectiveness without the disturbance of periodic maintenance, avoiding unnecessary loss of bacteria within the filter preventing high levels of ammonia and nitrite within the water. The major benefit of Kaldnes K1 media is the huge active surface area available for the bacteria to grow on compared to other types of media. This feature allows for smaller filter design while providing increased biological efficiency.

Main Benefits:

Creates a healthier environment for your fish
Even distribution of water throughout media (avoids dead areas within the filter normally associated with static type media filtration)
Old bio film is constantly renewed promoting new young heavy feeding bacteria
Many times more surface area than other types of filter media
Totally maintenance free and self cleaning
Oxygen rich environment gives improved oxygen transfer in moving bed technology
Removes nitrate NO3 - less green water, blanket weed and improved fish growth rates, etc.
Simply add more Kaldnes K1 media (up to 200 liters) to increase the biological filter performance
Open cell media for higher Nitrate removal rate
100 liters of K1 media will handle up to 0.5kg of food per day

Kaldnes Moving Bed™ Technology is included with Evolution Aqua's newest product, the Nexus. This combines both a mechanical and biological filter in one compact unit. It can also be used within Proline Professional, a system of stainless steel tanks that combine both mechanical and biological filtration.
