Care and maintenance of the JUWEL Filter System
Maintenance of the 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.
Important - Cleaning or replacing the blue filter sponges will affect the bacteria
cultures. We recommend therefore, that only one of the sponges at a time is cleaned or
replaced, never at the same time.
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.
Care and Maintenance
The JUWEL Aquarium Power head requires very little maintenance but we recommend
that you check it regularly to ensure optimum performance.
In order to maintain the power head, please follow the following steps:
1. Disconnect the heater and the power head from the power supply and allow the
heater to cool for approx. 30 minutes.
2. Remove the heater and place it on a non-flammable, safe surface.
3. Remove the nozzles from the power head.
4. Remove power head and adapter from the filter system.
5. Turn the adapter to the right to free it from the power head. Check that the rubber
seals do not show any sign of wear and tear. In case of doubt we recommend to
replace the adapter to ensure continuing optimum performance.
6. Remove the power head adapter from the motor and remove the impeller.
7. Clean and check all parts, in particular the impeller for wear and tear especially the
magnet.
Thereafter please reassemble the power head and reposition it back into the filter.
Recommendation:
With exchange of the impellers 400, 600 and 1000 the flow rate can be varied.
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.
