Kaldnes K1 Media/Micro 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 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.

K1 Micro Kaldnes
K1 Micro is specifically designed for use in bead filters, conventional pond filters and aquarium filters. K1 Micro has the same wheel shaped design as K1 Media, but it has an increased protected surface area of 950 m2 per m3.
The wheel shaped structure of K1 Micro is designed specifically to create the most effective environment for the nitrification process to take place. As K1 Micro media matures, bacteria colonises in the “quiet areas” of each piece of media helping to improve nitrification / de-nitrification. This enables a well-balanced biological equilibrium to be sustained in your pond to keep fish healthy and the water crystal clear.
The small size of K1 Micro makes it ideal to be used a replacement for beads in a bead filter. Not only will the vast 950m2 per m3 protected surface area maintain a bio-film that helps to improve nitrification, water quality and clarity, but K1 Micro can offer many more benefits:
Increased protection for the bio-film
K1 Micro retains the bio-film within its wheel shaped structure.
Improved solids handling
A static bed of K1 Micro packs tightly together with areas for solid particles and fines to be captured, helping to reduce TDS levels.
Increased flow rate
K1 Micro allows enough water to flow evenly through media rather than tracking around a “clump” of beads. This means that flow rates are improved when using “like for like” pumps.
Reduced back pressure
The improved flow also reduces the back pressure or resistance inflicted on the pump. In turn this improves the pumps’ efficiency and may even result in the need for a lower rated pump which will ultimately save you money!
During a cleaning process, the bio-film remains protected within the K1 Micro.
Semi buoyant media
K1 Micro is a semi buoyant media which makes it ideal for a bead filter.
