Care and maintenance of the JUWEL Filter System
The JUWEL Filter System requires very little maintenance if you follow the following
instructions.
- 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 particles.
- Replace the black activated 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 impurities
from the water will be removed. Please note that the chemicals which are absorbed by
the activated carbon contained in the sponge, will be released to the water again if
the change intervals are too long.
- If the filter wool and the activated 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 3-6 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 time, but rather successively in
an alternating manner.
You do not need to worry about the liquid dirt accumulating at the bottom 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. After the filter system is back in operation, the water will soon
clear again.
- In order to allow a proper level of micro-organisms in the filtration system it is
recommended to exchange the sponge every 6 weeks. The nitrate removal sponge
contains bacteria, which will after a while reduce the nitrate level in the aquarium
significantly.
Important:
Always use original JUWEL Aquarium filter media to ensure the optimum
performance of your system.
Maintenance of the pump JUWEL Eccoflow in the filter system
Bioflow 3.0, 6.0, 8.0
The pump JUWEL Eccoflow should be checked with regard to functionality and cleaned
at regular intervals (at least once a month).
Please proceed as follows to that end:
1. Disconnect all electrical devices of the aquarium from the power grid.
2. Remove the outlet nozzles.
3. Remove the pump from the separation wall of the filter.
4. Disconnect the adapter (A) from the motor by turning it counter-clockwise and
remove the impeller.
5. Thoroughly clean all components. It is particularly necessary to remove the impeller
from the chamber and remove deposits and dirt from the chamber itself as well as the
impeller. The function of the pump will be impaired otherwise. Also check the impeller
for damage and possible signs of wear of the magnet.
After that, please reinstall the pump in reverse order in the filter.
Recommendation:
In order to ensure that the power head operates at its optimum and maintains its
low noise level, we recommend to check and potentially replace the parts subject
to wear and tear, such as the impeller and the adapter.
All spare parts are available from your local JUWEL Aquarium retailer.
Safety instructions:
Never operate the power head out of water.
Always unplug the power head from the power supply before removing it from the
filter.
The power head is intended for indoor use and for use in fluids up to 35°C.
Never repair the electrical cord or plug. In case of damage replace the complete
power head.
