Sera F 400

Adjustable internal filters F are created on the basis of submersible adjustable pump P and the performance is naturally regulated. Inlet pipe connected to the inlet, runs water through fine-meshed sponge. Chicken wire sponge prevents the entrainment of larvae and juveniles inside the pump and, at the same time, removes the fine particles from the water. The sponge is formed, the biologically active area for nitrifying bacteria. Included suction cups are used to attach the filter.
