Oase BioMaster Thermo 250 - Filter with Heater and Pre-Filter for up to 250 Liters

The Oase BioMaster Thermo 250 filter is an interesting proposition for demanding aquarists for whom a large volume of filtration media and the high efficiency of the pump are important. Made of high-quality material, where all components are perfectly fitted. The filter is equipped with a large, sponge prefilter, which can be easily cleaned without the need to open the entire container, which significantly facilitates its use and is one of its most important advantages. Another distinguishing feature among other filters is the heater built into the filter, with a power dedicated by the manufacturer. The Thermo250 version of the filter comes with a 150W heater in the set. Another advantage is the ability to easily adjust the pump's performance. A solid handle also allows for convenient carrying of the filled filter. The filter is equipped with filtration media in the form of sponges of varying porosity and Oase's patented Hel-X media for biological filtration. All media are located in dedicated filtration baskets. The baskets can be easily pulled out and filled with any filtration media in any order.
