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.

The holes are 18mm x 18mm so no they wouldn't be small enough to stop K1 media

Alfagrog
Alfagrog is a porous foamed ceramic material, which is lightweight, strong and inert.
It’s high surface area makes it the natural choice for colonisation by micro-organisms in biological filtration systems resulting in cleaner water.
The Alfagrog range of porous ceramic filter media is made under controlled conditions UK.
Selected clays and raw materials are rapidly sintered at high temperature to produce a foamed ceramic porous mass, which is crushed and sieved to a convenient particle size.
Alfagrog is available in a wide range of sizes giving the end user optimum media surface area in varying water flow rates.
The manufacturing process ensures that no substances are present to adversely affect the health of fish or plants. The material is pH neutral and can be used in both freshwater and marine applications.
Why is it so effective:
The key to effective biological filtration is choosing media with the highest surface area possible to allow beneficial bacteria to colonise and remove waste from the water. Alfagrog has an extremely high surface area by volume compared with other types of filter media on the market.
Alfagrog is very inert and soon colonises with beneficial bacteria. Alfagrog is made of a highly porous material that contains many thousands of tiny pockets in which bacteria can thrive making in an ideal material for biological filters
Its only draw back is its sharp on the hands when cleaning so please wear gloves..
Benefits over other filter media:
Kintama Bio Balls Filter Media
Kintama Bio Balls come with an extremely large surface area, designed to increase the biological capability of your filter. This aides in the removal of harmful ammonia and nitrogen, keeping your water in as best a condition as possible.
These are suitable for adding to any standard biological filters, and will drastically increase the efficiency of your filter, and enable it to hold much higher levels of beneficial bacteria.
Kintama balls will kill harmful bacteria, whilst also preventing the growth of algae, and also stabilising pH levels. They are highly porous, so they can rapidly remove the harmful elements within the pond, including heavy metals.
Sizes available:
Japanese Matting
Japanese Matting, probably one of the best of all the filtration media which is available in the UK today ..
Japanese Matting is extremely inert and easy to service, Japanese Matting is available in sheet form and can be cut to the desired sizes to fit your filter chamber by using an Angle Grinder or better still an ordinary Circular Saw but be careful and wear protective glasses and watch those fingers unlike the fins on our Koi fingers don’t grow again.
Black Knight Spawning Brushes
Pack of 2 specially designed soft spawning brushes each brush measures 1.5m by 140mm diameter.
Spawning is made easy with the help of these specially designed brushes. The breeding season is normally from April to July depending on the weather.
Place the Spawning Brushes just below water level, one above the other, at the edge of the pond, this will
encourages your fish to spawn, usually in the early hours.
Spawning takes several hours with the eggs sticking to the brushes.
After spawning, separate the brushes from the broodfish to avoid the eggs being eaten.
Place the brushes in filtered water of the same temperature and the fry will hatch in 3-6 days.
Small fish should be kept separate until they are large enough to be introduced to the pond.
Please Note: These spawning brushes are made from a soft material that won’t harm your fish. DO NOT USE filter brushes for this purpose
Pumice stone Filter Media is now being used extensively as an alternative to traditional koi pond filter media in trickle filters and trickle towers .Pumice stone Filter Media is inert and rapidly colonises with beneficial bacteria which help cleanse the pollutants. It is highly porous making it the ideal media for biological filters of all kinds. Efficient biological filtration depends on the media of choice having an adequate specific surface area (SSA), adequate voiding and water retention time. Pumice Stone Filter media has a massive surface area and is therefore ideal in this application. It can be used as a direct replacement to other ceramic based filter media.
Kusuri Lithaqua
Kusuri Lithaqua is a marine mineral with a high content of minerals, trace elements and carbonates. It brings them into your pond and thereby adjusts the mineral balance and improves the water quality. Use it as pond substrate for bacteria to grow on and for fish to play in, or use it as a filter medium.
Modern multi-chamber filters contain mainly plastic media. Those are excellent supports for bacteria but they do not add anything to water quality. It is important to fill at least one filter chamber (preferably the last chamber) with Kusuri Lithaqua. It provides an enormous surface area for bacteria 10 to 20 times more than most plastic filter media) and provides the bacteria with essential nutrients.
Kusuri Lithaqua neutralises acid pH and helps to restore carbonate alkalinity.
Lithaqua is a marine mineral high in trace elements and carbonates, ideal for raising KH values. A superb filter media of porous construction, allowing a huge surface area for the growth of beneficial bacteria.
Modern filter chambers contain many and varied plastic media, these provide good support – but Lithaqua goes one stage further. Not only do the beneficial bacteria draw on nutrients from the mineral support, the media has a massive surface area up to 20 times greater than most plastic media.
Lithaqua is a biological media not intended for mechanical stages.
Use Lithaqua in a clean water chamber after mechanical removal of waste. Lithaqua is far more efficient than crushed oyster shells, and the high level of carbonates will improve carbonate alkalinity in soft water regions, neutralising low acid pH and buffer swings in pH.
Mountain Tree Spawning Brush
The spawning brush emulates natural koi spawning environment. During the spawning period, koi are sensitive to the environment. Without a comfy, soft home, they may spawn on hard rocks and walls. Thus providing them a comfy home for eggs growth is essential part of success spawning.
During this special period, koi are sensitive to the environment. Without a comfy, soft home, they may spawn on hard rocks and walls. Meanwhile, touching coarse material in a pond can lead to a risk of injury or unsuccessful spawning.
The Mountain Tree Spawning Brush is made of soft stainless steel coupled with appropriately dense nylon filaments. Fish will feel a smooth, comfortable surface that they can lay eggs on.
Black Knight Filter brushes
Black Knight Filter brushes are designed as a pre-filter for removing coarse waste and/or as a biological filter medium. Any design of filtration chamber will suit these brushes and they are easily removed for cleaning.
Black Knight filter brushes are made from the very highest quality Hydrotek polypropylene twisted into two stainless steel wires to form a cylindrical brush with a loop at one end for hanging. The other end is capped with a plastic knob for safety
Black Knight brushes are by far the most efficient and user-friendly product for removing suspended particles from your pond water.
