Mechanical filter material for fresh water
It 'a filter material, that is a substrate for bacteria (bacteria in the aquarium filter are used to decompose the fish waste and to eliminate the powerful poisons that are created during the organic decomposition). Being in an aquarium the concentration of organic matter decomposing very high in relation to the quantity of water, it is obvious that we need a bacterial culture very consistent and very active. Since these bacteria bound to a substrate is obvious that this substrate must be the most 'big as possible. The effectiveness of a filter in an aquarium is given solely by the ability to provide optimal conditions for the bacteria settlement.
For biological and mechanical filtration in all freshwater aquariums
The very high porosity creates optimal living conditions for nitrifying bacteria and other microorganisms. Before first use the evening biopur forte must be rinsed thoroughly.
