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 litres. No complete cleaning 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.
EASYCLEAN PREFILTER MODULE: No more bothersome dismantling of the filter – simply remove the pre-filter module, rinse and replace
PRACTICAL: Venting button for effective water suction – to get started quickly and easily during installation and after cleaning
LARGE FILTER VOLUME: The combination of highly effective biological filtering with Hel-X and mechanical/biological cleaning with filter sponges is ideally coordinated to ensure healthy and clear aquarium water. The water flows through the pre-filter first, ensuring an extra-long service life
SAFE: The shut-off mechanism and safety lock prevent unwanted water leaks during filter cleaning
ECONOMICAL & QUIET: Runs quietly and doesn't use much power
OPTIMUM FILTRATION: Fine 45 PPI pre-filter sponge to optimise mechanical filtration of coarse dirt and prolong the lifespan of biological media
ADJUSTABLE: Control the flow on the filter or via the adapter set
