Biological FilterMedia for Freshwater and Marine
Availability: 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.
Natural porous filter media with quiescent nitrifying bacteria phials which supplies more adequate areas for colonization of bacteria than plastic balls, cubes or sponges.
Fits into all canister filters as well as into internal and external bio filter
