Media Grids
Media Grids A most useful aid for anyone building their own filtration system these can be placed at a level that provides a void of water underneath the media itself and keeps the media out of any debris that may have gathered in the filter. It supports the media and is quite robust and is a must really can be fixed together and cut to size using simply a fine toothed wood saw or angle grinder. Size:

Hel-X
Oase Hel-X 13 Bio Media
Following rigorous Research & Development, OASE Engineers in Germany have successfully re-developed the Oase Hel-X Bio Media to further increase its biological settlement surface area by an additional 13%, resulting in the launch of Oase Hel-X 13 Biomedium. Oase Hel-X 13 consists of individual housings which allow beneficial aerobic bacteria to settle and breed inside the protected casings, helping to biologically break down soluble waste within the OASE ProfiClear Premium Moving Bed Filter Modules. Oase Hel-X 13 allows a greater amount of bacteria to be contained within the same filter volume, resulting in more rapid breakdown of food and fish waste within the filter system. 25 Litres of Oase Hel-X 13 Biomedia now has the capacity to biologically break down 170g of food/day. Oase Hel-X 13 can be used on any Filters to significantly increase their biological capacity but has been specifically designed for the OASE Pond Filters . Quantity: 25 Litres

Kaldnes K1 Media
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

K1 Micro Filter Media
Kaldnes K1 Micro Filter Media
K1 Micro Filter Media K1 Micro Filter Media 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.

ECO Pond Chip
ECO Pond Chip 14L
ECO Pond Chip Thanks to a further optimized surface structure and a diameter of now 25mm, we have succeeded in increasing the biologically activatable growth area for nitrifying, pollutant-degrading bacteria. The laboratory for nanostructures at the University of Bielefeld found a protected surface of 4370 m² per cubic meter at the new Eco Pondchip. It is also our goal to achieve the highest possible active bacteria population in the smallest possible space. As a result, considerably smaller biofilters can be produced and considerably lower costs can be achieved. Only 90 liters of Eco Pondchip are capable of biodegrading a daily feed quantity of up to 1 KG . Why, therefore, Several cubic meters of static biofilters? In addition to a considerably lower cost and effort compared to static biofilters, the moving bed technology guarantees a much better inflow and utilization of the surface compared to static biofilters. An undesirable channel formation, as occurs in many static biofilters over time, is also avoided with the permanently self-cleaning moving bed technology. 14 litres of ECO Pond-Chip media has a surface area of 61m2 - equivalent of 110 litres of K1.
