The Seachem Algae Scraper is an innovative 3-in-1 cleaning tool designed for both glass and acrylic aquariums. It combines three interchangeable cleaning heads in one: a metal blade for stubborn algae on glass, a plastic blade suitable for glass and acrylic, and a soft pad for delicate acrylic surfaces. The lightweight, ergonomic handle provides a comfortable grip in multiple positions. Its white color improves algae visibility during cleaning, and the floating design makes it easy to retrieve. The retractable blade housing ensures safe storage when not in use.Seachem Algae Scraper+ glass cleaner in two different sizes: 31 cm length and 46 cm length+ 3-in-1 design: metal, plastic & soft pad+ ergonomic handle for flexible use+ retractable blade housing for safety+ floats for easy retrieval+ white design improves algae visibility+ hanging hole for convenient storage
