Product Information

The Juwel Bioflow Filter system includes many intuitively designed features which make it stand out from the crowd. It provides plenty room for excellent mechanical, chemical and biological filtering and ensures a long services life and less maintenance. The filter's design means accessing the pump and heater is simple and the use of special filter cages makes it easy to remove and clean the filter media.

Fitted with Eccoflow circulation pumps for high efficiency and silent operation, the Eccoflow can be adjusted so its performance matches the size of the filter system by 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.

The Bioflow filter system does not rely on hose connections which can reduce performance, often leading to leakages it is the safest way of filtering the water in your aquarium.

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. 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.
