Description:
SUBSTRAT PRO 0.25L:
Eheim`s new superior biological media that improves and optimizes the
performance of Ehfisubstrat. It is for highly active water purification with
intensive biological decomposition of harmful substances. For use in all
canister filters. Can be used in all applications like in any filter system,
extra media for wet/dry sumps and in power filter media containers. It can also
be used as a replacement media for the Eheim AquaBall. It is pH & KH neutral so
it does not affect the water chemistry. It has a larger pore structure to ensure
optimum bacterial colonisation and delays the silting-up of the pores (for much
longer intervals between cleaning).
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.
