These replacement cartridge kits are a direct replacement for the removable cartridge used in the Seachem Algae Scraper tool and include both a metal blade and soft pad. Blades and pads will wear out with use and should be replaced regularly to maintain effectiveness and avoid damaging glass and acrylic.
