Oase BioMaster Thermo 250 external filter for tanks up to two hundred and fifty litres. Made from high quality materials the Bio Master is robust and also has a very modern look. Designed to provide mechanical, biological and also chemical filtration if you wish. External filters are in general much the same but the Oase Bio Master Thermo 250 differs slightly. The Bio Master comes equipped with an easy to clean pre filter that can be cleaned without opening the filter. The pre-filter consists of high grade foams that trap most of the debris.  The idea is that the debris removed by the pre filter extends the service interval of the main filter.

The Oase BioMaster Thermo 250 main filter.

The filters main section features two foam filter stages prior to the Hel-X media filled bio’ stage.  Hel-X 13, specially designed for use within the Oase Profi Clear Premium Moving Bed Module and Oase Profi Clear Premium Compact range of Drum Filter systems. So I would swap that out for a much better media, such as Seachem Matrix  Or Eheim Substrat Pro. Pretty standard view in the trade and hobby.
