Alfagrog is a porous foamed ceramic material, which is lightweight, strong and inert. Due to Alfagrog’s extremely high surface area it acts as a highly efficient biological filter media. Through the colonisation of micro organisms, Alfagrog helps to improve water clarity and quality by collecting and breaking down harmful fish waste. Alfagrog has an extremely high surface area by volume compared with other types of filter media on the market making it very popular with pond keepers.
Alfagrog is pH neutral allowing it to be used in both freshwater and marine applications.
