BioMaster² 850 External Aquarium Filter

Introducing the NEW and improved Oase BioMaster² 850 External Filter, suitable for providing effective filtration for aquariums up to 850 litres. Engineered for reliability and longevity, the BioMaster² multi stage canister filter features an optimum combination of mechanical and biological filtration to produce clean and healthy water for your fish. The new model features enhanced flow optimisation with an increase in flow rate of up to 25% compared to the previous models.

Each BioMaster² has an EasyClean Pre Filter module which can be easily removed from the canister for cleaning without the need to dis-assemble the whole filter. This innovative Pre Filter section now consists of premium 10PPI grade filter foams which remove suspended debris as the water passes through, extending the service life of the biological media.

The Oase BioMaster² Filters features a further 2 mechanical foam filtration stages above a biological stage which utilises Oase's highly effective Hel-X 13 Biomedia to complete the advanced and thorough cleaning process. Hel-X 13 is aptly named because it has up to 13% more biological settlement area compared to the original successful Hel-X Biomedia. This results in cleaner, clearer and ultimately healthier water due to the greater amount of beneficial bacteria contained within the filter which provide a more rapid breakdown of debris and waste particles.

Further innovative features include an automated shut off and safety lock mechanism, which prevents water from escaping when the Pre Filter Module is removed or when performing filter maintenance. An integral priming button allows for fast and easy start up during installation or after cleaning. The BioMaster² also allows for easy flow regulation via integrated outlet flow control.

Choose from either the Oase BioMaster² or BioMaster² Thermo edition - The BioMaster² Thermo includes all the great innovations of the BioMaster², but also discreetly incorporates the Oase Aquarium HeatUp Heater which allows for a fully adjustable temperature control. The Oase Aquarium HeatUp can also be easily retro-fitted to your existing BioMaster².
