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.
