The Seachem Algae Scraper is designed with versatility in mind. With three retractable blades: metal, plastic, and soft pad, it is suited for both glass and acrylic aquariums. It is lightweight and features an ergonomic handle making it comfortable to hold in multiple positions. In addition, it floats for easy retrieval. Finally, its white color makes it easy to see the algae you want to remove and when you’ve effectively removed it.
This Algae Scraper has a 3 in 1 design. There is metal blade to easily remove tough algae in glass aquariums. Not for use on acrylic. Then there is a plastic blade that is safe for use on glass and acrylic. Use care at gravel line to avoid scratching acrylic. Lastly, there is a soft pad as a first choice for acrylic aquariums. Easily removes algae from scratches.
Also, this Algae Scraper has a retractable blade. It allows to safely hide blade when not in use; easily switch between metal blade and soft pad (simply slide the cartridge out of the scraper head, flip, and re-insert); and choose from two blade positions/heights.
