Brand: Sera Model: PrefiX Filter Hose size: 16 / 22mm Container size: 1.6l Sera PrefiX Filter PRODUCT DESCRIPTION: The Sera PrefiX Filter allows you to increase the filtration capacity of the connected filter by up to 1.6 liters thanks to two filter baskets that can be used in different ways. This motorless filter can, for example, be used as a pre-filter in case of turbidity, as a quick filter in case of poisoning or as a biofilter to increase the filtration capacity of small external filters. The filter can be connected to a pump or an external filter using sera 16/22 mm hoses. It is also possible to connect several PrefiX filters in series. When using fine-grained filter media, it is recommended to use bags for sera filter media bags 1 or 2.
