Oase BioMaster Thermo 850 - Filter with heater and pre-filter for up to 850 liters.

The Oase BioMaster Thermo 850 filter is an interesting option for demanding aquarists who value a large volume of filter media along with a high pump performance. Made from high-quality materials, all components are perfectly fitted. The filter is equipped with a large sponge prefilter that can be easily cleaned without the need to open the entire canister, which significantly facilitates its use and is one of its most important advantages. Another distinguishing feature compared to other filters is the built-in heater with power dedicated by the manufacturer. The Thermo600 version of the filter comes with a 300W heater included. Another advantage is the easy regulation of the pump's performance. A solid handle also allows for convenient transportation of the filled filter. The filter is equipped with filter media in the form of sponges of varying porosity and the patented Oase biological filtration media called Hel-X. All media are located in dedicated filter baskets. The baskets can be easily removed and filled with any filter media in any order.
