Oase BioMaster Thermo External Filter (250/350/600)

Oase BioMaster filters are engineered in Germany for the most rigorous requirements. These external filter meet the highest demands in water filtration and filter cleaning. The combination of highly effective biological filtering with Hel-X and mechanical/biological cleaning with filter sponges ensures healthy and clear aquarium water. The BioMaster is suitable for aquariums with a volume of 250 to 600 litres.

No complete cleaning needed: the EasyClean pre-filter chamber enables convenient filter cleaning. The automatic shut-off and safety lock prevent unwanted water leaks, e.g. when removing the pre-filter module. A practical venting button makes the water suction highly effective and allows for a quick and convenient start.

The complete set includes filter media, hoses, adapters, suction and discharge pipes as well as the water diffuser. The BioMaster Thermo comes with an adjustable heater.

Key Features

Quick and Easy Maintenance
The EasyClean pre-filter module means no more bothersome removal of the filter, the pre-filter module is simply taken out, rinsed out and reinserted. The unique shut-off automation and safety locking mechanism prevents undesired water escaping when removing the pre-filter module. The vent button for effective water intake, giving a fast and easy start up when installing and after cleaning

Chamber for Heater
The included HeatUp adjustable heater has been designed alongside the BioMaster thermo to fit perfectly into a slot in the unit. This leaves the top of the heater protruding from the top so it can be adjusted to the correct temperature without having to open the filter canister. 

Large filter volume
The combination of highly effective biological filtering with Hel-X and mechanical/biological cleaning with filter sponges is ideally coordinated to ensure healthy and clear aquarium water. The water flows through the pre-filter first, ensuring an extra long service life.
