The OASE BioMaster² Thermo Canister Filter sets a new benchmark in aquarium filtration, delivering exceptional water clarity, energy efficiency, and easy maintenance. Designed for freshwater and saltwater aquariums up to 850 litres, this next-generation filter combines powerful biological and mechanical cleaning with user-friendly features for stress-free aquarium care.

At the heart of the BioMaster² is a four-stage sealed filtration system, featuring Hel-X biological media and filter foams for maximum surface area and pollutant breakdown. The unique EasyClean pre-filter chamber allows fast cleaning without dismantling the entire filter, prolonging the lifespan of the main foams and reducing maintenance time.

The integrated HeatUp heater (150W to 400W, model dependent) keeps your aquarium at a stable temperature while eliminating the need for an in-tank heater, reducing clutter and keeping aquatic life safe. Optimised water flow and an improved connection set deliver higher flow rates while consuming less energy than previous models.

Each BioMaster² Thermo comes as a complete set, including filter media, hoses, adapters, intake and outlet pipes, and a water diffuser—ready to set up and run straight out of the box.

Perfect for both hobbyists and professionals, the OASE BioMaster² Thermo is the ultimate filtration solution for healthy, crystal-clear aquarium water.
