A scientifically designed media created to provide the most effective enviroment for the nitrification process to take place.
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.

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) gives the bacteria the means to grow, whilst the Kaldnes media provides maximum surface area for the bacteria to colonise 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 colonise. Within the wheel, is a protected surface, which enables colonies of bacteria to naturally follow their life cycle, maturing and dying, in turn fuelling 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.
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.
K1 has four times more surface area when static than jap mat and many times more efficient when chaotic.
Each 100ltrs will handle up to 1.5kg of food per day.
We use this media in our filters and have been very pleased with the results. It is easy to convert an existing filter or vortex to accomodate K1 and we will be pleased to assist you with your calculations and conversion.
To calculate Liters of media required for a filter chamber:-
length(in's) x width(in's) x depth(in's) = Sq.Inches
x 0.0164 = liters
x 50% = liters of media recommended
To calculate Liters of media required for a straight side vortex chamber:-
radius(half diameter) x radius(half diameter) x 3.14(pi) x height(top of cone to water level) = Sq.Inches
x 0.0164 = liters
x 50% = liters of media recommended
