Magnetic Aquarium Cleaner Tetra Magnet Cleaner Flat S – compact magnetic glass cleaner

Tetra Magnet Cleaner Flat S is a compact magnetic aquarium glass cleaner designed for routine removal of algae and light debris from aquarium panes. The device consists of two magnetic parts: an outer handle for manual guidance and an inner cleaning element that floats against the inside glass. It enables external cleaning without placing hands into the water and is suitable for small or shallow aquariums where a slim profile and gentle action are required.

Advantages

The compact design provides easy manoeuvrability on narrow panes and close-to-surface tanks while maintaining firm magnetic contact. A flat cleaning surface reduces the risk of scratching and helps to reach corners and edges more effectively than bulkier units. Because it operates from outside the aquarium, the cleaner minimises disturbance to aquatic life and avoids direct hand contact with tank water during routine maintenance.

Suitable for

• Small home aquariums with glass panes
• Shallow tanks and nano aquaria
• Frequent light maintenance to remove soft algae and surface deposits

Key specifications

• Compact, flat magnetic design for slim-profile tanks
• Outer handling unit for external operation and inner cleaning element for internal contact
• Cleaning surface suitable for routine removal of soft algae and light debris
• Designed for use on glass aquarium panes

How to use

Place the inner cleaning element gently against the inside glass and align the outer handle on the corresponding outside position so the magnets attract. Move the outer handle smoothly over the glass surface to remove algae and deposits; pressure should be moderate to maintain contact without forcing. For corners and edges, guide the outer unit slowly to let the inner element follow. After use, separate the two parts while holding them over a towel to avoid accidental drops and rinse both components under fresh water to remove residues.

Usage recommendations

Use the cleaner regularly for light maintenance rather than attempting to remove thick or calcified deposits; for heavy encrustations, use dedicated treatments or a mechanical scraper with care. Regular inspection of the cleaning surface for wear and replacing it when worn will help prevent scratches on the glass.
