Alfagrog Pond Filter Media AKA Supra Bio Media In The USA

Alfagrog Low Cost High Performance Biological Pond Filter Media

It is important to understand surface area in terms of biomedia choice because you will save yourself lots of money by doing so. In simple terms biological filters are only really as good as the bio media used. The more beneficial bacteria living on the bio medium in your bio-filter the purer your pond water will be. These microscopic bacteria convert toxic ammonia from fish metabolic waste, rotting vegetation and excess fish food in to nitrites. A different set of micro bacteria then converts the nitrites into nitrates (fertiliser for pond plants).

Choosing the correct biomedia has a major impact upon your pond filter's performance and for the majority of garden fish ponds using gravity discharge filters, Supra is by far the best pond filter media to use. Alfagrog (known as Supra in the USA) is a porous ceramic filter media that is made under controlled conditions in Staffordshire, England. It has been specifically engineered for pond filters in the fish farming industries. Depending upon the size of the Alfagrog particles the area for bacteria colonization can be up 100 times that for most types of plastic balls or coils provided as standard in many manufacturers products.
