Alfagrog - 15 kg Bag Pond Filter Media

Alfagrog is a porous ceramic pond filter media which is made under controlled conditions in Staffordshire, U.K.
Alfagrog pond filter media has a very high surface area making it an ideal material on which micro organisms can adhere and boost biological decomposition of pollutants.
Alfagrog is a Volcanic rock and has been used now for several years with a great deal of success .. it is very inert and soon colonises with beneficial bacteria ...
Alfagrog is made of a highly porous material that contains many thousands of tiny pockets in which bacteria can thrive making in an ideal material for biological filters

Ja etter hva jeg mener å huske er det lavastein som er tromlet litt, slik at det har rundere kanter.
Lavastein har alle de samme fordeler og ulemper som alfagrog.
