  • Brush head from a battery-powered toothbrush. I used one for an Oral Action toothbrush. It has a drillable extension on the top that allows for a deeper hole for attachment pin. Other brands may work as well.
  • 3/8 in wood dowel (or larger) -but make sure it will fit in your drill chuck.
  • 1/8 in wood dowel
  • Small saw
  • Drill
  • Pliers
  • Super Glue

Use the same 1/8 in drill bit used for the brush hole to drill a 3/8 in. deep hole in the dowel cut to appropriate length for your aquarium. Don't make dowel any longer than necessary.
