Scraper is a multiple use blade cleaner. The 15cm wide blade makes it easy to remove even the most resistant calcareous algaes from the aquarium glass. The removable blade protector also acts as a squeegee for cleaning the outside of the aquarium glass. A unique feature of the scraper is the hinge which allows the blade head to be turned through 180°. This facility allows the user to clean the aquarium even when the tank decoration, such as rocks or roots, are very close to the glass.
