Bioflow Mini An original Juwel part with Juwel Media and Juwel Powerhead (heater is not included). Replacement Bioflow Super Filter for Juwel Aquariums with 42.5cm height. Includes Media and 300 l/h powerhead for tanks up to and including 80L. Energy 4.4 Watt Filter dimensions L51 x W96 x H224 mm. Cable 143cm The JUWEL Bioflow filter system stands out from the crowd with its extra-large filter volumes. This gives plenty of room for excellent mechanical, chemical and biological filtering and ensures a long filter service life and longer service intervals. The filter\'s design offers you easy access to the pump and heater and the use of special filter cages makes it easy to remove and clean the filter media. Excellent filtering using the bipolar current principle JUWEL Bioflow filter system\'s unique bipolar current principle makes it possible to achieve different flow velocities, which helps to create the extraordinarily high filtering performance of the Bioflow system. For mechanical and chemical filtering in the upper part of the filter, a relatively fast flow velocity is particularly useful. A slower flow velocity, on the other hand, is useful in the lower part of the filter, to ensure optimum development of anaerobic bacteria, which are vital for biological filtering. Ideal flow and integrated heater JUWEL Bioflow filters come fitted with a highly efficient, silent Eccoflow circulation pump, with performance adjusted to the size of the filter system using scientific criteria. Bioflow Filters are also compatible for use with JUWEL heaters, which are perfectly embedded in the water circulation, ensuring an even distribution of heat through all areas of your aquarium. (Heater sold separately) Safety first – the water should stay in the aquarium! The Bioflow filter system does not rely on hose connections which can reduce performance, often leading to leakages. The Bioflow system is the safest way of filtering the water in your aquarium.
