The Aqueon Small Magnetic Algae Scraper uses a dual-part magnet system to clean the inside glass from outside the tank. The curved cleaning pad works on flat and curved surfaces, and the scrubber can detach from the magnet to fall straight down for easy retrieval. Best for compact tanks or setups where a gentle touch is preferred.

Best for: small tanks with glass panels; beginners who want a simple cleanup tool with reliable retrieval. Caution: ensure the magnet does not slip when scrubbing vertical edges, and avoid using on rough or deeply etched surfaces.

Aqueon Medium Magnetic Algae Scraper

The Aqueon Medium model adds a larger cleaning pad and a stronger magnet for easier control on bigger panels. Like the small version, it cleans both flat and curved glass surfaces and resumes a straight-down retrieval if detached. This choice suits mid-sized tanks needing more scrubbing power while staying affordable.

Best for: mid-sized glass tanks; users who want a straightforward upgrade from the small version without changing brands. Caution: heavier magnets may require a steadier hand on larger tank walls to avoid skipping or slipping on slick surfaces.

Best for: nano tanks and planted tanks that require quick maintenance. Caution: the high-strength magnet can be challenging to handle in very small spaces; keep it away from sensitive electronics near the tank in certain setups.

Best for: standard glass tanks where ease of use and float retrieval are priorities. Caution: may not be ideal for very thick glass or encrusted algae that require heavier scrubbing force.

Buying Guide: Key Purchase Considerations

What tank thickness will you clean? Magnetic strength and compatibility depend on glass or acrylic thickness, as well as panel size. Measure your tank wall and choose a pad and magnet combo that matches the thickness.

Which cleaning surface do you need? Look for dual-sided cleaners (fabric and abrasive) if algae tend to adhere firmly. For acrylic tanks, ensure blades are suitable to prevent scratching.

Is retrieval important? Floating designs and detaching pads help avoid wet hands and minimize disturbance to fish. Consider models with easy retrieval or floating recovery.

What about ease of use? Ergonomic handles, non-slip grips, and balanced magnet pairs reduce fatigue during longer cleaning sessions.

Are extras needed? Some cleaners include multiple blades or detachable scrapers. Verify compatibility with your tank material and thickness to avoid accidental damage.
