Size: 50 Internal Filter


The aquarium corner internal filter cleans water in aquariums with a volume of 50 to 200 litres. Integrated outlet nozzles ensure even surface movement and enough oxygenation. At the same time, they prevent the formation of film residue. The pump runs very smoothly and saves energy. It has a compact filter unit which can easily be removed for cleaning, while the pump unit stays put. The high volume of the filter sponges ensures effective mechanical and biological filtration. The filter can easily be attached to the corner of the aquarium using suction cups. The BioPlus also comes in a thermal version with a built-in heater.

Filter media: Filter foam can be removed on a modular basis – ideal for time-delayed, bacteria-friendly cleaning.

Easy cleaning: The magnetic bracket makes it easy to remove and attach the filter cartridges.

Flexible: Enjoy the flexibility of switching between outlet nozzles and a water outlet for an optimally coordinated surface movement.
