Fish-Mate Bio SUPRA also Called Alfagrog

Alfagrog or Supra Pond Bio Filter Media.

This filter medium called Alfagrog in the UK and Supra in the USA is by far the best low cost filter biomedia on the market. It has about 40 times more bacteria holding capacity than all plastic cylinder types of biomedia. The media is ceramic and is finely sintered so it makes an excellent easily cleanable mechanical filter medium also.
