Alfagrog Filter Media

  Alfagrog
  What is 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 of Alfagrog over other filter media:
 
  • Extremely high surface area
  • Highly porous
  • Inert, pH neutral
  • Lightweight
  • Available worldwide
  • Economical
  • A variety of grade sizes available: 25mm / 40mm / other sizes on request
   
 
 
   
  The Alfagrog range of porous ceramic filter media is made under controlled conditions in Staffordshire, 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 Alfagrog 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.
  The table below shows that in theory approximately 20 times more volume of foam would be required to attain the same level of filtration as Alfagrog E40 and almost 40 times as much as Alfagrog E25. This means a smaller filtration unit can be used when using Alfagrog to attain the same results as a much larger unit filled with inferior and often more expensive filter media.
  Other applications
  Alfagrog can also be used as decorative aquatic gravel, aquarium landscaping and in a wide variety of applications. Alfagrog is produced in a wide range of sizes, contact us for more information.
