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) 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.
If you would like to convert one of your existing filter chambers to the
Kaldnes media then we have a TWO SPECIAL CALCULATORS (Used by kind
permission of Trevor Pearson at the East Riding Koi Company) which
will help you Calculate the amount of Kaldnes you will need.
