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.

Ideal for biorb aquariums, Alfagrog filter media’s high surface area makes it an ideal material on which microorganisms can adhere and boost the biological decomposition of pollutants.

Used to maximise the optimum media surface area with high water flow rates. The manufacturing process, which produces the ceramic media, ensures that no substances are present to adversely affect the health of fish or plants, Alfagrog is ideal for use in filtration systems, as aquatic gravel or aquarium landscaping.

Alfagrog is ideal for use in any biological filter system. It is very popular among koi keepers and commonly used in multi-chamber filter systems. Replacing plastic filter media with Alfagrog will massively increase the biological capacity of your filter.
