OASE BioMaster² 250 Thermo External Aquarium Filter – Ex Demo

The OASE BioMaster² 250 Thermo is a premium external aquarium filter designed to provide efficient mechanical and biological filtration while keeping maintenance simple. This ex-demo unit has been opened and fully tested to ensure it is in complete working order and is supplied in its original retail box.

The filter may show minor cosmetic marks or signs of handling associated with demonstration use, but these do not affect its performance.

Designed for aquariums up to 250 litres, the BioMaster² 250 Thermo combines highly effective Hel-X biological filtration with mechanical filter sponges to help maintain crystal-clear, healthy aquarium water. The integrated HeatUp 150 adjustable heater keeps the aquarium uncluttered by eliminating the need for a separate in-tank heater.

The innovative EasyClean pre-filter module allows quick maintenance without dismantling the entire filter. Simply remove, rinse and replace the pre-filter to keep the system operating efficiently while extending the service life of the biological filter media.

With a maximum flow rate of 900 litres per hour, quiet operation and an energy-efficient design, the BioMaster² 250 Thermo is suitable for both freshwater and marine aquariums. The filter is supplied complete with filter media, hoses, connectors, intake and outlet pipes, making installation quick and straightforward.
