Clean and healthy water
Plant or food residues and metabolic products affect the quality of the aquarium water. Good quality water is essential for the good health of the fish and plants in the aquarium. This quality can be achieved by special filters. These filters suck the water from the aquarium and extract impurities and other waste. Filters also provide an ideal living environment for depolluting bacteria.

Easy installation
The external filter is fully equipped and ready for connection. The built-in quick-priming system and suction-less filter start allows for easy installation. Filter media are also provided.

Easy maintenance
Regular replacement of the pre-filter avoids frequent cleaning of the rest of the filter. The large volume of the filter ensures a high capacity of biological filtration through different filter layers. The supplied biofiltration beads have different diameters, which promotes the self-cleaning effect.

Energy efficiency and safety
With their low consumption, CristalProfi filters allow a great saving of energy. The device consumes 31% less electricity than comparable predecessor models, while producing equally efficient water circulation. The flexible hose connection block is patented and equipped with a safety valve, it prevents any water leakage when disconnecting the filter. The JBL CristalProfi is TÜV tested.

New compared to the first generation JBL CristalProfi: the top filter basket has been completely redesigned for greater efficiency: instead of the small pre-filter plates on the outside, it is now twice the size and a single piece that serves as a pre-filter. The filter cannot therefore become clogged so easily, even in the event of a large quantity of impurities, and the cleaning of the pre-filters will be less frequent.
