High-performance internal filter

With EHEIM biopower you have a high-performance internal filter that never existed before: the spherical, all-round swivelling pump head, the modular design and other advantages of the aquaball concept. The special feature of biopower is that it offers multi-stage filtering like an external filter. The closed filter baskets are filled with highly efficient filter material (e.g. SUBSTRATpro). At the bottom is the suction basket with filter cartridge for mechanical-biological pre-filtration. The water sucked in at the bottom is pumped upwards through the various filter layers and finally cleaned and returned to the aquarium.
