Rock Filter Media 15kg from 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 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.

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.

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 can also be used as decorative aquatic gravel, aquarium landscaping and in a wide variety of applications.
Larger size pieces can be used as a substitute for live rock.

Extremely high surface area
Highly porous
