Maintenance And Care - JBL CristalProfi i80 Handbuch

Note: In aqua-terrariums with low water levels, the filter can be simply be placed on one of the flat sides on the bot-
tom. The filter will remain in position due to its weight. There is also the option, for the internal filter lying on the bot-
tom of the aqua-terrarium by attaching the side of the filter perpendicular to the floor with a halved magnetic holder
outside. Simply click the magnetic holder into two pieces at its hinge.

Starting up the filter
Turn the swivel water outlet in the direction required and install the wide jet pipe, diffuser or spray bar as wished.
Now plug the filter to the mains power supply.
Tip: We advise against using the spray bar in aquariums containing plants as too much CO
expelled from the water. The best results are achieved using the wide jet pipe with the opening just below the surface
of the water to produce a moderate surface water flow.
Note: Should you replace an existing aquarium filter with JBL CristalProfi Internal Filter, we recommend running
both filters, the new and the old, for the first 2 weeks parallel in the same aquarium before dismantling the "old" filter.
This ensures that the new filter has a sufficiently large colony of cleansing bacteria and avoids harmful nitrites occur-
ring 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. 300 l/h 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
the vital plant nutrient, is
