OASE BioMaster² Thermo 350 AU External Canister Filter (94688)

The OASE BioMaster² Thermo 350 is the next generation of OASE's premium BioMaster external canister filter — now with enhanced performance, improved water flow design, and an integrated HeatUp 200W adjustable heater for complete all-in-one filtration and heating. Designed for aquariums up to 350 litres, the BioMaster² Thermo 350 delivers exceptional mechanical and biological filtration with the added convenience of an integrated heater — eliminating the need for a separate in-tank heater and keeping your aquarium clean and clutter-free.
