OASE BioMaster 850 Canister Filter - 1550 L/H | External Aquarium Filter

The OASE BioMaster 850 Canister Filter is the flagship model in the BioMaster range, engineered for large aquariums up to 850 litres. Designed to meet the highest demands in filtration performance and maintenance convenience, it delivers powerful, consistent, and reliable water purification for professional and advanced aquarium setups.

At the core of the BioMaster 850 is its advanced multi-stage filtration system, combining highly effective Hel-X biological media with mechanical filter sponges. This system ensures thorough removal of waste, organic debris, and harmful substances while supporting beneficial bacteria growth to maintain a stable and healthy aquatic environment.

The innovative EasyClean pre-filter chamber allows for quick and convenient cleaning without the need to dismantle the entire filter unit. This significantly reduces maintenance time and ensures uninterrupted filtration performance. The integrated automatic shut-off and safety lock system provide added security by preventing water leaks during servicing.

With an impressive 1550 LPH flow rate and a maximum head height of 2.2 metres, the BioMaster 850 delivers powerful water circulation and optimal oxygenation, making it ideal for larger aquariums with higher biological loads. The integrated priming button ensures easy and efficient start-up, simplifying installation and operation.

Supplied as a complete installation kit, the BioMaster 850 includes filter media, hoses, adaptors, suction and discharge pipes, and a water diffuser. Its external canister design keeps equipment out of sight, maintaining a clean and visually appealing aquarium environment.

The filter is compatible with the OASE HeatUp 400 heater, allowing seamless integration without visible in-tank equipment. Alternatively, users can choose the BioMaster Thermo 850 version, which includes the heater for a complete all-in-one solution.

Suitable for both freshwater and saltwater aquariums, the OASE BioMaster 850 is a professional-grade filtration solution designed for maximum performance, reliability, and ease of use in Australian aquarium systems.
