Magnetic Glass Cleaner Sera SE-32838 for Aquariums — Floating 10 mm Glass Thickness

Magnetic Glass Cleaner sera SE-32838 is a floating magnet cleaner designed for aquarium glass with a thickness of 10 mm. The tool consists of an inner cleaning pad and an outer magnetic handle that operate through the glass, allowing the interior surface to be scrubbed while the user controls the exterior part. Its floating inner unit prevents loss if detachment occurs and the design is suitable for both freshwater and saltwater aquaria for routine maintenance of algae, biofilm and mineral deposits.

Advantages

The magnetic coupling enables cleaning without immersing hands in the tank, reducing disturbance to water and inhabitants. The floating inner piece ensures retrieval if the magnet slips and simplifies handling on taller tanks. The cleaner is sized for 10 mm glass, providing stable contact and effective scrubbing action on the inner surface while the external handle remains dry. Materials and magnet placement are intended to offer steady movement across vertical and slightly curved glass panes.

Suitable for

• Routine removal of algae and biofilm from aquarium glass
• Maintenance of freshwater and saltwater tanks with 10 mm glass
• Quick spot-cleaning between full water changes
• Cleaning vertical or slightly curved aquarium panels

Key specifications

• Designed glass thickness: 10 mm
• Floating inner cleaning unit to prevent sinking
• Two-part magnetic construction: inner scrubber and outer handle
• Suitable for use on both freshwater and marine aquaria

How to use

Place the inner cleaning unit gently against the inner surface of the aquarium glass at the desired starting point and align the outer magnetic handle on the corresponding outer surface. Move the external handle in smooth vertical or horizontal strokes to guide the inner scrubber across the glass, applying moderate pressure to remove algae or deposits. If the inner unit detaches and floats, retrieve it from the water; if it sinks to the top surface, the floating design keeps it accessible. Rinse the cleaner under freshwater after use to remove debris and prevent salt or residue buildup.

Usage recommendations

Use the cleaner regularly to prevent thick algae layers that require stronger mechanical removal. Avoid using excessive force on acrylic panes or decorated surfaces; confirm compatibility with non-glass materials before use. Store the tool dry and out of direct sunlight to preserve magnets and cleaning surfaces.
