Sera Scraper Blades Acrylic and Sponge

Replacement acrylic and sponge blades for Sera scraper XL and XXL allow quick and thorough removal of algae and other dirt on the aquarium glass. Each set contains three different tools that are easy to change - one stainless steel blade for glass, one plastic blade for acrylic, and a sponge for soft layers - for cleaning the inside aquarium glass appropriately and very gently. Even persistent algae can be removed without effort.
