The aquarium cleaner features an improved long-lasting cushion surface. Made with rare earth magnets for high durability during cleaning, it removes even the most stubborn coral algae. The blade side has three contact points, creating a safety gap between the cleaner and the glass, minimizing the chance of sand trapping and scratches. The unique orientation buoyancy keeps the magnets facing the glass for easy retrieval.

• Includes a stainless steel blade for glass tanks.
• Blade replacement is recommended every 3-6 months for optimal algae scraping.
• Designed for smaller tanks up to 1/4" (6mm) or about 25 gallons.
