Evolution Aqua Kaldnes K1
Incorporating Kaldnes Moving Bed Process
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 .
Developed by Professor 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 to circulate the media
throughout the vessel. This flow is created by pumping air through the K1.
How it Works
Maturing the Kaldnes biomedia is important because a delicate ecosystem is naturally developing for the bacteria involved in the nitrification process. Fish are required to generate waste which the bacteria survive on. The bacteria colonies the new media without the need for additional chemicals. When established, your Kaldnes should be brown in color.
Nitrification Process
Oxygen and food (fish waste) gives the bacteria the means to grow, whilst the Kaldnes media provides maximum active surface area for the bacteria to colonise more than other types of static media. It is this process, which removes harmful ammonia and nitrite from the water.
As the Kaldnes media chaotically circulates within the sump, it
causes old dead bacteria on the outside, to be removed making space for
new younger heavier feeding bacteria 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 provides the correct mix
of both young and mature beneficial colonies providing a more
consistent filter performance, whilst improving water quality,
encouraging healthier fish .
Maturing Process
The maturing process needs monitoring closely to ensure that levels of pH, ammonia and nitrate are within acceptable parameters for your fish. Usually after a period of between 4-6 weeks the beneficial bacteria will have colonized the media to a satisfactory level to deal with the waste produced by your fish.. This period may extend depending on local water condition, temperature and stocking density.
Self Cleaning
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.
We ourselves have been running K1 in our fish room and show tanks sumps for 3 years now .
