FILTER MATERIAL FOR PIC 3
Ceramic Ring Filter Sponge Biochemical Cotton Bio-Ball
The delivered filter material is considered a standard equipment for your aquarium external filter.
Basically, it applies from bottom to the top:
1.stage: mechanical / biological filtration in part
2.stage: biological filtration
3.stage: chemical filtration (activated carbon, turf, phosphate Ex etc.)
As for 4-stages filters, you can extend by a mechanical or biological filter stage, depending on the
filtering requirements.
Ceramic Rings
Ceramic glass rings for the internal and external aquarium filters.The filter media, with mechanical
filtration, are used for removing suspended particles. The ceramic rings cause a water turbulance in
the filter basket due to their special form and large surface.By this way floating particles can accumu-
late during the descent and coarse dirt particles are removed from the water cycle.
This filter material creates optimal conditions for filter bacteria which reduce nitrite peaks better than
other filter materials.
Filter Floss - Filter Fleece
Filter media like fleece, floss or sponges are essential in modern aquaristics.
Coarse dirt particles are absorbed by means of filter floss, sponges reduce the nitrate, clean the water
of chemical impurities and provide ideal conditions for the settlement of filter bacteria.
Bio Balls
Bio balls are used in aquaristics as mechanical and biological filter mediat. These balls offer bacteria a
large area for their accumulation and are considered to be high performance filter media for powerful
filter systems. In contrast to other filter media, bio balls have a virtually unlimited life-span which
makes them a popular and cheap filter medium for pond filter systems, trickle filters and chamber fil-
ters.
Activated Carbon - optional
Activated carbon is used in aquaristics to filtrate urinary and humic substances, pesticides, toxins and
similar residues and to provide for clean aquarium water. Additionally the ozone and the chlorine con-
tent of the water is reduced through the use of the activated carbon.
The activated carbon is particularly suitable for the pre-treatment of tap water, for water clouded with
suspended particles and for filtering out residues after a medication treatment..
During a medication and algae treatment one should not use the activated carbon. However, after said
water treatment the activated carbon is indispensable for removing remnants.
We do not recommend to leave the activated carbon in the filter tray over a long period. After the me-
dia filter (activated carbon ) reaches its absorption capacity, there is the possibility that absorbed
harmful substances are washed out and end up in the aquarium water.
When purchasing a new aquarium filter or after a complete cleaning, the beneficial bacteria must be
enriched again.
There are special bacteria cultures that can be added to the aquarium filter, thus facilitating the start.to
4 stages by adding a me-
chemical or biological filter stage
