Replacement Blades for Aqua Medic Scraper - 5 pack The scraper is a
multiple use blade cleaner. The 5.9" (15cm) wide blade makes it easy to
remove even the most resistant calcerous algaes from the aquarium
glass. The blades are manufactured from corrosion resistant hardened
steel. 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 for 180°.
This facility allows the user to still clean the aquarium even when the
tank decoration - such as rocks or roots, comes very close to the glass.
