Two Little Fishies MagFox is a powerful magnetically coupled brush for cleaning aquarium hoses. It can easily be moved back and forth within hoses of diameters 3/8" or larger, and removed without getting one's hands wet.
The MagFox makes it possible to reach and remove algae or deposits at any position in long lengths of hose, something not possible with foxtail brush.
Caution:Small parts may present choking hazard. Keep out of reach of children. Strong magnets! Keep away from computers, monitors, credit cards and watches.
