The ultimate convenience among the external filters for aquariums. The external filter meets the highest demands in water filtration and filter cleaning. The combination of highly effective biological filtering with Hel-X and mechanical/biological cleaning with filter sponges ensures healthy and clear aquarium water. The BioMaster is suitable for aquariums with a volume of 250 to 850 liters. No complete cleaning is needed: the EasyClean pre-filter chamber enables convenient filter cleaning. The automatic shut-off and safety lock prevent unwanted water leaks, e.g. when removing the pre-filter module. A practical venting button makes the water suction highly effective and allows for a quick and convenient start. The complete set includes filter media, hoses, adapters, suction, and discharge pipes as well as the water diffuser. The BioMaster is available with or without an adjustable heater.
