The Tunze Care Magnet Nano is a compact algae cleaner designed for precision aquarium maintenance. Featuring dual plastic blades of varying lengths, it applies differential pressure to tackle stubborn algae while remaining gentle on glass and acrylic surfaces. The slim profile sits discreetly in your tank without disrupting décor, and the 3mm magnet offset prevents sand jamming. Dual-blade technology rolls algae into edible particles for fish rather than dispersing debris. Suitable for glass thickness 6–10mm, it handles flat and curved panes without damaging silicone seals. Includes replacement blade and eight interchangeable colored end caps for customization. Low magnetic slip-resistance ensures reliable operation during cleaning sessions.
