The Oase BioPlus Thermo 50 is a compact internal aquarium filter with an integrated adjustable heater, providing both filtration and heating within a single unit. Designed for aquariums up to 50 litres, it helps maintain stable water conditions while reducing equipment inside the tank.

The filter features high-volume foam media that supports both mechanical and biological filtration, helping to remove debris while providing surface area for beneficial bacteria. A third stage of filtration can be added using optional fine filter fleece or activated carbon, allowing additional chemical filtration if required.

An integrated adjustable diffuser nozzle distributes water flow across the aquarium surface, helping to break surface tension and support oxygen exchange. With a pump output of 350 litres per hour, the BioPlus Thermo 50 provides steady circulation suitable for smaller aquariums.

Maintenance is simplified with the EasyClean mechanism, allowing the filter unit to be removed and cleaned without disturbing the pump section. This design reduces maintenance time and helps minimise disruption within the aquarium.
