Kaldnes K1 Media

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 for fish keepers and is exclusively distributed worldwide by Evolution Aqua. The media is engineered in a wheel shape and is slightly positively bouyant. This allows a small amount of water flow to circulate the media throughout the vessel. This flow is created with your air pump and air stones or diffuser etc.

How it works :

Maturing the Kaldnes bio-media is important because a delicate eco-system is naturally developing for the bacteria involved in the nitrification process. Kaldnes media provides the 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.

How it is different to other media :

As the Kaldnes media moves within the filter, it causes the old dead bacteria on the outside to be displaced. This makes space for new younger heavier feeding bacteria to rapidly colonise. Within the wheel is a protected surface which enables colonies of bacteria to naturally follow their lifecycle, of maturing, dying and then fueling the latter stages of the nitrification cycle. Kaldnes has been designed to provide the best possible habitat for both young and mature beneficial bacterial colonies.

Incorporating Kaldnes Moving Bed™ Process

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.

This amazing bio media which is reputed to be 10 times more efficient than matting and lowers Nitrate! 100 litres can process 1/2 kilo of high protein food per day! Designed to be moving at all times, Kaldnes K1 is self cleaning, owing to its continual motion in both water and airflows and is also therefore massively oxygenated thus rendering it super efficient.

Kaldnes has also proven to be a fantastic static media to improve mechanical filtration as it does not block, but is capable of removing very fine solids and is very easy to clean.

Surface Area 800 Square metres per cu.m Kaldnes K1 is a buoyant media.

K1 Micro Filter MediaK1 Micro Filter Media

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!

Improved cleaning



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.

Evolution Aqua K + Media

Evolutions Aqua’s new filtration media, the K+ Media is designed and manufactures in house. Added to the K1 media family, the new Evolution Aqua K + Media is moulded with minerals for faster beneficial bacteria development. K + media also has a much larger surface area than any other media. Evolution Aqua K + Mediais the advanced filtration media for moving bed filters.

Evolution Aqua K Plus Media

  • Class leading total surface area 1,3540 m2 per m3
  • Total protected surface area 1,025 m2 per m3
  • Moulded with minerals for faster beneficial bacteria development
  • Available as floating for MBBR or sinking, ideal for down - flow filters
  • Size - 10.5 mm Dia
  • Length - 8 mm

Unlike foam, matting, or other forms of static filtration media, the K+ Media is designed to move freely within your filter. The constant chaotic movement of the air from your pump, causes the media to self clean and thus requires no maintenance.

This allows the filter to reach optimum effectiveness without the disturbance of periodic cleaning, avoiding unnecessary loss of bacteria within the filter. 50 Litres of K + media will handle up to 250 grammes of food per day.
