The fine material of the woolen mat catches fine impurities not trapped
by the other filter media. It is recommended that you replace the
woolen mat once a month.
Activated Carbon
The activated Filter Carbon chemically removes substances such as
pesticides and remedies from the water and adsorbs odors and
substances that cause muddying and yellowing of the water. This filter
medium is to be used on demand on a short term basis. It is
recommended that you replace the filter carbon every month.
Tetratec
Useful bacteria are bred in the small spaces of the ball. Impurities are
then divided and neutralized biologically. The balls are reusable as
long as the dirt on the surface can be removed by washing with
tank water.
Tetratec
The fine sponge surface allows the production of useful bacteria,
which break up dirt particles and biologically filter impurities. It is
recommended that you change the sponge once every six months.
Tetratec
These ceramic rings physicaly filter impurities while distributing the

through the filter. They should be replaced when dirt on the surface
of the rings cannot be removed by washing with tank water.
After washing the media replace them in the filter media
container as per the original order (refer to page 2 or 3).
