BioMaster 250/350/600/850 OASE

The ultimate convenience in an aquarium exterior filter. External filters meet the highest demands for water filtration and filter cleaning. The combination of high efficiency biological filtration with Hel-X and mechanical/biological cleaning and filter sponges ensures healthy and clear aquarium water. BioMaster is suitable for aquariums with a volume of 250 to 850 liters. No need for thorough cleaning: The EasyClean pre-filter chamber makes it easy to clean the filter. Automatic shut-off and safety lock prevent accidental water leaks, such as when removing the pre-filter module. The practical vent button makes water suction very efficient and allows for quick and easy start-up. The complete set includes filter media, hoses, adapters, suction and discharge pipes and a water diffuser.
