"The AquaScum 2003 is an all-purpose, self-cleaning maintenance free salt water purifier that is guaranteed to even extend the life of your aquarium fish. The AquaScum is programmed to scan your tank environment every 5 minutes?"
Peach, reading the manual of the AquaScum 2003

The AquaScum 2003 is a device that is bought by the dentist for his office fish tank after Dr. Sherman enters his office one day to find the tank dirty (caused by Nemo, who successfully jams the filter). It is designed to automatically scan the tank for any filth to remove with its laser beam. Rather than taking his fish out and putting them into bags so that the dentist cleans the tank like he presumably once used to do, Dr. Sherman instead installs the device, thus sabotaging any chance of his fish, especially Nemo, from escaping the office.

At the end of the film, the device stops working, despite having a lifetime guarantee, much to the chagrin of Dr. Sherman, who is then forced to clean the tank himself by taking the fish out and putting them into bags (however, the fish manage to escape the office this time).


  • 2003 may be a reference to the year in which Finding Nemo was released.
  • There is an easter egg on Disc 2 on the DVD showing a commercial for this filter.
  • Gurgle seems to hate the Aquascum the most.
