The Tetra IN plus internal filter ensures clear water in almost every aquarium. All filters have at least one double chamber, so the filter sponges can be cleaned alternately or the filters can be filled with different filter media. In addition, the filter can remain in the aquarium when cleaning, as the chambers have a practical removal device for added convenience.
The 180° swivelling outlet nozzle ensures a controlled outflow, the flow rate of which can be adjusted easily. The integrated and adjustable Venturi system allows additional oxygen to be added to the pool. Thanks to their simple and compact design, the IN plus internal filters can be placed well in an aquascape and can be attached quickly and easily with the included suction cups. The filters are available in five different versions, which are suitable for small and also larger aquariums. In addition, the filter chambers can be equipped with separately available filter media.
