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.
Note: 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!
Lift the complete filter vertically out of the aquarium and wait until all the water has drained from the bottom valve.
Remove the foam cartridge, as described in part (1) and rinse in lukewarm water (25 °C). Do not wash the foam
cartridge too thoroughly otherwise too many beneficial bacteria will be rinsed away.
Guideline: Stop washing the foam cartridge when only slightly dirty water can be seen when the foam cartridge is
squeezed. When using several foam cartridges to filter, do not wash all the cartridges at the same time, but at alter-
nate intervals.

Function and replacement intervals of the foam cartridges
Foam cartridge (JBL UniBloc):
Medium-pored foam cartridge for effective biological filtering with ideal conditions for colonisation by cleansing
bacteria. The grooved shape (T profile) allows for long use with little reduction in flow. Careful cleaning is required
approximately every 1 - 2 months. Replace the old foam cartridge after cleaning 2 to 3 times. For filters with several
cartridges, only clean or replace the foam cartridges at alternate intervals.

Cleaning the impeller and casing
Remove the cover from the impeller casing by pulling gently vertically upwards.
Take the impeller out of the casing.
CAUTION: the impeller is held in the casing by magnetic force. Take appropriate care when removing the impeller,
particularly to avoid any injury to fingers. The stainless steel shaft is fixed and cannot be replaced.
Clean the impeller casing, impeller and cover with a suitable cleaning brush, then rinse in clean water. Limescale can
