The BioMaster² 250 Thermo 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 150 adjustable heater is included in the scope of delivery. The BioMaster² 250 Thermo 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. In addition to the HeatUp adjustable heater, the complete set contains filter media, hoses, adapters, intake and outlet pipes and is ready for immediate use.
