::Filtra 1 – Biological FilterMedia for Freshwater and Marine

In stock


ELOS Filtra1 has been formulated not only to provide a natural substrate, but also to slowly dissolve as a result of natural solubility and close-proximity bacterial respiration, simulating the processes at work in sediment found in nature. ELOS Filtra1 is a terrigenous material composed of minerals naturally occurring in marine habitats, and therefore brings the hobbyist one step closer to providing a truly representative piece of the natural biotopes.


  • absolutely natural porous filter media
  • accompanied with quiescent nytrifing bacteria phials
  • supplies more adequate areas for colonization of bacteria than plastic balls, cubes and sponges
  • ideally fits into all canister filters as well as into internal and external bio filter
