Micron, internal filter for aquariums up to 75 litres of capacity. Micron is provided with a floating rotor system, complete with a device that avoids the part to wear out and with an exclusive water flow control system, to allow you to adjust the filtering depending on the volume of water in the aquarium. With its high-adherence suction cups, Micron is ready for wall fitting. The filtering action is carried out by an active carbon filter with zeolite which ensures perfectly clean water for at least thirty days.
