## Description

The OASE BioMaster 2 850 is the next generation of our best-selling BioMaster filter—reimagined with updated features, making it our most efficient and user-friendly filter yet. The OASE BioMaster 2 delivers advanced, quiet, and user-friendly external filtration for freshwater or saltwater aquariums. With curved inlet/outlet tubes and adjustable flow control, it offers optimized circulation and performance over earlier models. Its EasyClean pre-filter module removes separately, reducing mess and extending the life of your main filter foams. Priming is simple, and the detachable aquastop allows for easy maintenance without disturbing tubing. The BioMaster 2 uses a 4-stage sealed filtration path that includes fine and coarse foams, activated carbon, and Hel-X Biomedia for superior mechanical, biological, and chemical filtration. Though it doesn’t include a built-in heater, it’s designed to easily integrate the OASE HeatUp heater—reducing in-tank equipment and protecting aquatic life from direct heat exposure. High-quality materials, robust impeller, enhanced ventilation, and rubber feet that dampen vibration, all allow the filter to run quietly. Safety locks and spill-free design make it easy and clean to maintain. Ideal for aquariums up to 225 gallons, the BioMaster 2 is Italian-made, German-engineered, UL certified, and backed by a 4-year warranty (3 + 1 with registration).
