Versatile and user friendly external filters for freshwater aquariums

These powerful but at the same time energy saving external filters with an extensive accessory range are ready for connection and immediately biologically active. The filter baskets ensure an optimal filter media layer structure and easy access. Intake and outlet of the filters are designed in a way that the hoses can be disconnected by a multi-function valve for cleaning purposes.

These robust filters are characterised by quiet operation and a long lifetime. All filters include the high performance filter medium sera siporax Professional and the biologically activating sera filter biostart.
