Care and maintenance of the JUWEL Filter System
The JUWEL Filter System requires very li le maintenance if you follow the following
instruc ons.
bioPad
Replace the white filter wool pad once a week. If you have large fish, then this may
require changing slightly more frequently. This will ensure that the filter sponges will
not be clogged by larger dirt par cles.
bioCarb
Replace the black ac vated carbon sponge every 4-6 weeks. Again, if you have large
fish then this may be to be more frequent. This ensures that any chemical impuri es
from the water will be removed. Please note that the chemicals which are absorbed by
the ac vated carbon contained in the sponge, will be released to the water again if the
change intervals are too long.
bioPlus coarse/bioPlus fine
If the filter wool and the ac vated carbon sponge are replaced as suggested, then it is
sufficient to carefully clean or replace the coarse blue sponges at 6-12 weeks and the
fine blue sponges at 3-9 months only.
- Cleaning or replacing the blue sponges or the Cirax filter medium affects the impact
of the bacterial culture. For that reason, it is recommended not to clean or replace the
blue sponges and the Cirax filter medium at the same me, but rather successively in
an alterna ng manner.
You do not need to worry about the liquid dirt accumula ng at the bo om of the filter
housing. Normally, this dirt contains important biological substances which enhance
the water quality.
Please do not worry if some dirt gets into the water during the cleaning process
causing cloudiness. A er the filter system is back in opera on, the water will soon
clear again.
Nitrax
In order to allow a proper level of micro-organisms in the filtra on system it is
recommended to exchange the sponge every 8 weeks. The nitrate removal sponge
contains bacteria, which will a er a while reduce the nitrate level in the aquarium
significantly.
OPTIONAL:
Amorax
Amorax is a highly efficient filter medium made of natural zeolite. It quickly and
effec vely binds ammonium, thereby preven ng the forma on of ammonia and
promotes the vitality of your fish. Replace the JUWEL Amorax every 3 months.
Carbax
Carbax's excellent absorp on proper es permanently and quickly bind
discoloura ons, odours and toxic substances and ensure crystal-clear water. We
recommend replacing JUWEL Carbax every 2 months.
Cirax
Cirax is a biological filter medium which creates the perfect colonisa on condi ons for
useful bacteria, due to its large, highly porous surface. We recommend changing
JUWEL Cirax every 12 months.
Phorax
JUWEL Phorax is a highly effec ve filter medium used to break down phosphates in
your aquarium. This effec vely reduces the growth of algae and can contribute to
improved plant growth. Change JUWEL Phorax every 2 weeks.
