Oase have brought their great expertise into the aquarium hobby and have looked for some gaps in the already saturated market. Their idea was to make an affordable reliable external cannister filter with an integrated heater and prefilter.

The pipe size is 16/22mm which is fairly standard so connections with other equipment is easy. Operation is extremely quiet, and priming is made easy with the built in primer. Oase BioMaster Thermo 600 comes equipped with all the pipework and media to get it up and going though we would look at improving the media. Main filter media volume is a generous 6.8 litres and the prefilter volume is 0.6 litres. The warranty is 3 + 1 years that requires you registering it for the extra year.

Oase BioMaster Thermo 600 filter for tanks up to six hundred litres. Made from high quality plastics 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 all much the same, but the Oase Bio Master Thermo 600 differs slightly. The Bio Master comes equipped with an easy to clean pre filter, easily cleaned without having to open the main 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 pre filter also helps to maintain crystal clear clean water.

The Oase BioMaster Thermo 600 main filter.

The filters main section features two foam filter stages prior to the Hel-X media filled bio’ stage.  Hel-X 13, 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 definitely swap that out for a much better media, such as Seachem Matrix  Or Eheim Substrat Pro.  A fairly standard view in the trade and hobby. The way that the filter is supplied will without doubt provide sparkling crystal clear water and despatch Nh4 and No2. However, if you desire the decline of No3, then better media such as below should used.
