The BioMaster² 250 external filter fulfils the highest demands of water filtration and filter cleaning. The combination of highly effective biological filtration by Hel-X and mechanical-biological cleaning by filter sponges ensures healthy and clear aquarium water. The HeatUp adjustable heater can be easily retrofitted if required. The BioMaster² 250 is suitable for aquariums with a volume of up to 250 litres. The EasyClean pre-filter chamber enables convenient filter cleaning. The automatic shut-off and a safety valve prevent unintentional water leakage, e.g. when removing the pre-filter module. A practical priming button makes water intake simple and enables a quick and easy start.

No more bothersome dismantling of the filter – simply remove the pre-filter module, rinse and replace
