Seachem Algae Pads are non-scratch cleaning tools designed for glass and acrylic aquarium surfaces. Made from melamine foam, these pads utilize micro-abrasive technology to effectively remove algae without harming your aquarium’s surfaces. They are particularly effective at removing algae from scratches and are chemically inert, containing no soaps or detergents. Their white color contrasts against dark algae, making it easier to see when areas are fully clean.
