Eheim EHFILAV Freshwater Biological Filtration Media, 5L Information




Biological Filter Media
A build-up of toxic nitrogenous wastes is a natural result of all aquarium inhabitant`s life processes. In nature, the body of water is large enough to dissipate or dilute these wastes. Some will even be converted into usable energy by living organisms. Within an aquarium however, without a powerful biological breakdown of these toxins, the fish literally poison themselves. This is the reason why biological filtration is the most desirable of all aquarium filtration.

This type of filtration is the purification of the aquarium water by using living organisms, such as nitrifying bacteria. These desirable bacteria will attach themselves to all hard surfaces within the aquarium system. They use the toxins as a food, converting harmful toxins such as ammonia and nitrite into less harmful nitrate. Nitrate can then be removed by performing regular water changes.

After prolonged use, mechanical and chemical filter media will act in a biological manner. They provide some surface area for bacterial colonization but this is actually very limited. In order to provide the greatest amount of surface area for bacteria colonies, filter media such as EHFISUBSTRAT or EHFILAV should be used.

EHFILAV 5L: A naturally occuring porous volcanic rock which is ideal for biological filtration where large debris is present such as ponds and highly stocked aquariums. This natural product is pre-tested for impurities before pachaging to ensure that it is free of toxins.

Comments: Ehfilav has enormous surface area! I use these in my cichlid tanks' filters with excellent results. Since using Ehfilav I have enjoyed superior water quality and clarity. I have also noticed reduced algae. I use Ehfilav and Bio-Balls in alternating baskets of my filters while using the sponge pads included with the filters for mechanical filtration. I rinse the pads monthly. I fill the baskets used for Ehfilav by placing the baskets on newspaper, pouring the Ehdilav out of the bags into the baskets, then lifting the baskets and shaking gently above the newspaper. Then I rinse the Ehfilav which remains in the baskets. I use the small pieces that are left on the newspaper as decorative soil covering for my houseplants.
