  • Porous ceramic rock with large surface area
  • Ideal biological filter media for ponds and aquariums
  • Approximately 40mm pieces

 

Alfagrog is a pH neutral porous ceramic material that has a huge surface area and is ideal for pond and aquarium filtration. It is a lightweight material formed from clays and other raw materials that are then sintered at high temperatures resulting in this porous foamed ceramic.

Alfagrog has such a high surface area that you would need up to 20 times more volume of foam to create the same biological effect as this E40 Alfagrog media

  • Highly porous with large surface are for great filter bacterial growth
  • As a guide use 1 litre of Alfagrog per 1000 litres of pond water.
