Function and Replacement Time Frames for each Filter Media
13
Use only replacement Tetra EX filter media supplied by the manufacturer. It is recommended that
filter media be replaced in accordance to the specified periods.
Tetra FF Filter Floss Pad
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.
Tetra BB Bio Filter Balls
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.
Tetra BF
Biological Filter Foam
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.
Tetra CR Ceramic Filter Rings Physical Filter Media
These ceramic rings physicaly filter impurities while distributing the water
flow in a number of directions ensuring that water passes evenly 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).
14 Hose Cleaning
Dirt and algae build up on the inside of the hoses can reduce water flow. Flush out dirt and algae by
removing the pipes and flushing them with tap water.
