Media Grids
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:

Alfagrog
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. Benefits over other filter media:
  • Extremely high surface area
  • Highly porous
  • Inert, pH neutral
  • Lightweight
  • Available worldwide
  • Economical
  • Available in 15kg sacks
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 - sharp on the hands when cleaning ... so please wear gloves..

Kusuri Lithaqua Media Sack
Kusuri Lithaqua Media Sack
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.   Sack 300mm x 500mm

Oyster Shells
Oyster Shells
Oyster Shells have been used for years by Koi professionals to help with the pH of the water and to maintain optimal water conditions and is extensively used in Japan. Since the Oyster Shells will generally raise the pH level in your water, these should only be used in cases of low pH. Oyster Shell generally will raise the level of the pH. For those that ever ever been to Japan, Oyster shell is used extensively by the breeders in Japan, these soluble (soft) shells are used to stabilise the pH. Oyster shells stabilise the pH / KH-value which prevents pH crash. If the KH value drops to this starts to dissolve the shells until balance is reached again. Nitrifying bacteria also grows on the oyster shell.

Bacteria Home Media
Bacteria Home Media 10KG
Bacteria Home media is a high-grade filter medium made of porous bars of mineral rock. The rock is baked under very high temperatures. The media is suitable for different types of filter, but is especially effective in a bakki shower. High concentrations of good bacteria nestle in the microscopic pores in the rock. The bacteria improve the quality of your water and filter out any harmful particles such as nitrate, nitrite, and ammonia. The media increases the mineral and redox values of the water. It also enriches your pond with oxygen. This way, Bacteria Home media improves the quality of your water up to 16 times more effectively than do other filtration systems.

media bags
Media Bags
Filter Media Bags are a most useful aid to bagging up, for example, Flocor or Alfagrog. You could even soak k1 (Kaldnes) in these sacks to seed the media up! Made from a plastic resin base, these very strong sacks are ideal for all filter media and can be fully submerged without degrading of the material. Designed with a draw cord for quick sealing. The ideal solution for gaining simple access for periodic cleaning to the filter contents. Size 85 cm x 52 cm approx and is capable of holding 2 cu.ft of Flocor for instance.

Japanese Zeolite
Zeolite 10KG (SuperFish)
Zeolite reduces the Ammonia in your pond creating a healthier environment for your Koi. It works by trapping and absorbing Ammonia, extracting it from your ponds water. Ammonia is the nuber one killer of pond fish, maintaining a health level of ammonia within in your ponds ecosystem is essential, and this product can aid in this process. As it absorbs the ammonia, soaking in salt overnight will release the entrapped ammonia enabelling it to be reused. However, should you need to treat your pond with salt or other medications you must remove the Zeolite from your filter system as the entapped ammonia will be release back into your system. Quantity: 10 LTR  Please Note: You will need the media bags to put the zeolite in with this product.
