Juwel Carbon Sponge bioCarb, Jumbo XL

In your aquarium, all residents should feel as comfortable as possible. In addition to feeding and fertilising your aquatic plants, this also includes cleaning and regular partial water changes. So that your aquarium water is always as clean as possible and many useful bacteria colonise, you should use a good internal filter, such as the Juwel Bioflow internal filter.

The Juwel Bioflow has been scientifically tested several times by independent institutes and has long been one of the world's leading filter systems for modern aquaristics and has proven itself millions of times over. The Juwel Bioflow filter system is characterised by its particularly large filter volume. This offers space for excellent mechanical, chemical and biological filtering and ensures long filter service life and long maintenance intervals. The design of the filter also gives you easy access to the pump and heater, and the use of special filter baskets ensures easy removal and cleaning of the filter media.
The unique dual flow principle of the Juwel BioFlow filter system ensures that different flow velocities are achieved in the filter and thus contributes significantly to the exceptionally high filter performance of the Bioflow system. A comparatively fast flow rate is particularly advantageous for mechanical and chemical filtering in the upper filter area. A slower flow rate in the lower area of the filter, on the other hand, favours optimal development of anaerobic bacteria, which are essential for biological filtering.

Juwel Bioflow filters are equipped with a highly efficient and whisper-quiet Eccoflow circulation pump, the performance of which is matched to the size of the filter system according to scientific criteria. The Bioflow filters are also prepared for the admission of the Juwel heaters, which are thus optimally integrated into the water cycle and ensure even heat distribution in all areas of your aquarium. The Bioflow filter system does not require any performance-reducing hose connections, which are often the cause of leaks. The Bioflow system is the safest way to filter the water in the aquarium.

Each Bioflow system is equipped with five high-quality filter media. In second place are the carbon filter sponges, which serve primarily for biological filtering in the anaerobic area and are therefore an essential part of the Juwel filter system. You can easily replace the sponges. The carbon sponges absorb odours and turbid substances as well as toxic compounds in your aquarium and ensure crystal-clear water. The use of activated carbon in the form of a sponge ensures an even flow through the filter medium and ensures an extremely large and therefore effective surface. Thanks to these properties, the carbon sponges are also ideal for filtering out drug residues after the treatment period.
