The Hobby mesh bag is suitable for use with filter media and can be inserted into the filter as well as into the aquarium.

Occasionally, the use of different filter media is necessary to achieve stable water values and to adjust water values. With the Hobby net bag, the filter media can be easily separated from each other and are still optimally reached by the water flow thanks to the structure. They can be filled and used quickly and easily. The mesh bag can be used both in the filter and directly in the aquarium and, thanks to its handiness, does not clog any other filter mats or media.
