Alfagrog Bio-Filter Biomedia for Fish Ponds

it is important to understand surface area in terms of biomedia choice. You will save lots of money on your biofilter this way. The more bacteria you have in any pond filter the better your pond water quality will be. These bacteria transform toxic chemicals in the pond water secreted by the fish into plant fertilizer suitable for pond plants.

AlfaGrog in Pond Filters

The AlfaGrog range of porous ceramic filter media is made under controlled conditions in Staffordshire, U.K.

Selected 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.

  • High surface area
  • Strong
  • Inert
  • Porous

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 Alfacoral or Supra in USA pond bio media The wide range of sizes available enable the user 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 available in several grain sizes, ideal for the use in filtration systems, as aquatic gravel or aquarium landscaping.

Alfagrog is called Supra in USA . Alfagrog looks a bit like cinders, it is lightweight, comes in different sizes and you can literally blow through it because it is so porous.

AlfaGrog is manufactured in the U.K. by sintering selected fireclays at very high temperatures, resulting in a foamed ceramic porous mass. By crushing and screening the material a range of grain sizes are produced.
