Aquarium Magnet Cleaner Tetra TETRA Magnet Cleaner Flexible – magnetic glass cleaner for aquariums

Tetra TETRA Magnet Cleaner Flexible is a magnetic glass cleaner for aquariums designed to remove algae and deposits from the inside surface without the need to put hands in the water. The tool consists of a pair of opposing magnetic parts: an inner pad that contacts the glass and an outer handle that guides the movement from outside the tank. Its flexible construction allows the cleaner to follow slight curves and compensate for different glass thicknesses, making it suitable for routine maintenance of freshwater and marine aquariums to keep viewing panes clear and support stable water quality.

Advantages

The flexible magnetic cleaner cleans both sides of the glass at once: the inner pad scrapes away algae while the outer magnet holds and directs motion. No direct hand contact with aquarium water is required, reducing disruption to aquatic life and lowering contamination risk. The design adapts to curved panes and varying glass thickness, ensuring continuous contact and efficient removal of soft to moderate deposits. The product is lightweight and easy to handle, enabling regular maintenance with minimal effort.

Suitable for

• Routine removal of algae and soft deposits from aquarium glass
• Freshwater planted and community tanks
• Marine and reef aquariums for non-abrasive cleaning
• Curved or slightly bent aquarium panes where rigid cleaners do not conform

Key specifications

• Magnetic double-sided cleaner with inner and outer parts
• Flexible body to follow curved glass surfaces
• Designed for glass and comparable transparent aquarium materials
• Suitable for routine maintenance of freshwater and marine tanks
• Removes soft to moderate algae and deposits without chemicals

How to use

Place the inner magnetic pad inside the aquarium against the glass and align the outer magnet on the corresponding exterior surface. Move the outer handle slowly across the pane so the inner pad scrapes deposits away. For curved surfaces, maintain steady pressure and follow the curvature to keep continuous contact between both magnetic parts. Rinse the inner pad in aquarium water if heavy debris accumulates, and periodically inspect the cleaning surface for trapped particles to avoid scratching the glass.

Usage recommendations

Use the cleaner for routine maintenance rather than heavy-scale scraping of hard encrustations; avoid forcing the magnets across the glass if resistance is high. For stubborn mineral deposits or hard algae, combine mechanical cleaning with appropriate water treatment methods after consulting aquarium care guidance. Regular short cleaning sessions preserve visibility and reduce the need for intensive cleaning.
