If a conventional external filter and an internal filter are not suitable, the OASE BioStyle hang-on filter stands out with its own advantages: In comparison to a classic external filter, no hoses need to be laid during commissioning. A cabinet with the appropriate space for positioning the filter is also not re-quired here, and the hang-on filter does not take up any space inside the aquarium. The BioStyle filter offers a clear view of the underwater world.


  • Two filter stages for optimal cleaning:

    Biological and mechanical cleaning plus features that make maintenance so much easier, like the removable filter cartridge – these are just some of the benefits of the BioStyle hang-on filter.

  • Perfect fit:

    The adjustable spacers ensure that the BioStyle hang-on filter fits perfectly into the aquarium. Furthermore, the transparent intake pipe is telescopic.
