The Seachem Algae Pads are non-scratch algae pads for glass and acrylic. The melamine foam uses micro abrasive technology to easily remove algae from the sides of your aquarium. Their white color contrasts against dark algae making it easier to see when areas are fully clean.
Melamine foam is incredibly effective abrasive cleaner. It has a microstructure as hard as glass, but because of its open-cell structure it remains flexible. It performs on stains a lot like extremely fine sandpaper. In the aquarium, it easily removes algae by scraping with its extremely hard microscopic filaments.Features:
