Maintenance - GREENLINE CristalProfi 80 Benutzerhandbuch

Note: Should you replace an existing aquarium filter with JBL CristalProfi Internal Filter, we recommend running both filters,
the new and the old, parallel in the same aquarium for the first 2 weeks before dismantling the "old" filter. This ensures that the
new filter has a sufficiently large colony of cleansing bacteria and avoids harmful nitrites occurring in the transitional phase.

Regulating the water flow
The water flow can be regulated as required using the water flow regulator. To do this, hold the swivel water outlet and turn
the flow regulator to the right or left until the required flow rate is produced. The flow regulator is designed so that a minimum
flow rate of approx. 150 or 300 l/h (depending on the model) is maintained. In order to avoid damage to the pump, this rate
cannot be reduced.
Maintenance and care
All JBL CristalProfi internal filters are fully equipped with foam cartridges to provide clean and healthy aquarium water for
"normal" operation. The filters provide ideal conditions for the development of colonies of cleansing bacteria which play an
essential role in the breakdown of pollutants. The selection of pore size ensures that these bacteria can efficiently carry out
their task undisturbed for as long as possible.
Note: To solve problems (undesirable algae growth etc.), we offer a range of special filter materials designed for use with the
JBL CristalProfi Internal Filters in a specially constructed filter basket. (Section D.)
Caution: Regular maintenance and cleaning of the filters is vital to prevent a reduction in the pump capacity.

Cleaning or replacement of the filter material
Unplug the filter before any work is carried out on it!
To remove the filter, simply press the two buttons (PUSH) on the front side of the pump head simultaneously with your
thumbs and pointers and remove the filter from the aquarium glass. Lift the complete filter vertically out of the aquarium and
wait until all the water has drained from the bottom valve.
