Efficient Algae Removal on Glass Removes algae buildup from aquarium glass quickly with sturdy non abrasive scrubbing pads that clean without scratching the surface. Safe for Aquatic Life Made from aquarium safe materials with gentle, non abrasive surfaces to protect fish, plants, and decorations while tackling algae. Versatile Design Magnetic cleaners are ideal for glass tank walls, allowing cleaning from outside. Handheld scrubbers provide precision for corners and hard to reach areas. Easy to Use Magnetic models use an outer magnet with a cleaning pad and an inner magnet that moves along the inside of the tank, enabling thorough cleaning with minimal water contact. Practical Use Scenarios Regular maintenance of glass walls in freshwater or saltwater tanks. Cleaning corners behind decorations, filters, or hard to reach spots. Cleaning tall or long tanks by moving the outer magnet instead of leaning over the water. Compatibility and Performance Designed specifically for glass aquarium surfaces, delivering effective algae control with reliable performance and simple operation.
