Internal biological filter for aquariums from 200 to 400 litres. Sera Internal Biofilters B are very easy to look after. The huge filter volume is divided into three filter chambers and a separate compartment for an aquarium heater.
The Sera Internal Biofilters B are easy to install. There is no need to have any hoses hanging outside the aquarium. Included in the set is a Sera Submersible Pump.
The best effect is achieved when using Sera Siporax as a filter medium. For special purposes Sera Super Active Filter Carbon and Sera Super Active Blackpeat Granulate are recommended.
