BioMaster Thermo 850 External Filter

The BioMaster line of premium external filters boasts 4-stage filtration and is designed with sealed filtration pathways to ensure water travels the most efficient path through all filter media - creating optimal water quality and clarity. The BioMaster canister filter family is characterized by high filter performances and long service lives. The EasyClean features and advanced designs are perfect for maintaining a clean and healthy ecosystem for your fish and plants. The Thermo line has the added feature of an integrated heater. By integrating the heater into the filter, the amount of additional equipment seen in the aquarium is greatly reduced.

Precise Temperature Control

The BioMaster Thermo 850 features an integrated heater that provides precise and uniform temperature levels, reducing visible equipment inside the aquarium by housing the heater within the unit. This ensures a streamlined and aesthetically pleasing tank setup.

Efficient and Customizable Filtration

With its Easy Clean pre-filter module, maintenance is simplified and mess-free. The module can be removed separately, enhancing filter efficiency and extending the life of the main filter foams. Customize your pre-filter with options including coarse 30 ppi, fine 45 ppi, ultra-fine 60 ppi, and activated carbon 45 ppi filter foams for optimal performance.

No Mess Maintenance

The BioMaster Thermo 850 is designed for hassle-free maintenance with integrated safety locking features on the handle, pre-filter, and check valve in the inlet/outlet connection unit, ensuring no accidental spillage or messy maintenance procedures.

Advanced Filtration Pathways

Sealed filtration pathways allow for the full benefits of all four stages of filtration through this intuitive design. The Hel-X Bio Media offers an extremely large protected settlement surface (800m²/1000 liter) for beneficial bacteria to grow and thrive, enhancing biological filtration efficiency.

Superior Carbon Filtration

Carbon pre-filter foams absorb unwanted substances in the aquarium water, making replacements much simpler than using common granular carbon. This ensures cleaner water and healthier fish.

Adjustable Flow Control

The BioMaster Thermo 850 includes adjustable flow control for both the inlet and outlet, allowing you to customize the water flow to meet the specific needs of your aquarium setup.
