Answering the needs of hobbyists who want simple, effective algae control for acrylic tanks, this guide compares top acrylic-compatible magnet cleaners. These devices let you scrub and scrape without wet hands, and many are designed to float or stay securely attached. The best pick varies by tank thickness, acrylic vs glass, and how hard you scrub. Ideal buyers include new hobbyists seeking easy cleaning, reef enthusiasts with stubborn buildup, and busy fish-keepers needing reliable, hands-free operation.

Gulfstream Tropical AGU130A Mag-Float Acrylic Cleaner
The Gulfstream Tropical Mag-Float Medium is a buoyant acrylic cleaner designed to glide around corners without sinking. Its floatation makes operation easier and reduces the risk of losing the cleaning head. Best for medium-sized acrylic tanks where access to corners is important, and where a gentle float helps beginners control scrubbing pressure. Caution: Ensure the magnet remains clean to prevent reduced grip.
Aqueon Algae Scraper (Medium)
The Aqueon Medium Algae Scraper uses a magnetic system to clean from outside the tank, with a curved pad suitable for flat and curved surfaces. It’s a versatile choice for both glass and acrylic tanks. The scraper may separate from the magnet; it then falls straight down for easy retrieval. Best for hobbyists who want a flexible option across tank types, with reliable retrieval if detachment occurs.
Aqueon Aquarium Algae Scraper Mini
Compact version for smaller tanks or tighter spaces. The Aqueon Mini shares the same magnetic operation and retrieval feature as its medium sibling, making it a good fit for small to mid-sized acrylic setups. Best for nano tanks where a slim tool helps you reach crevices without crowding the tank.
Flipper Standard Algae Magnet Cleaner
The Flipper cleaner combines a scrubber and scraper in one device with a slim profile ideal for reaching edges and corners on glass or acrylic up to 1/2″ thick. Best for users who want a compact, all-in-one cleaning tool that can handle stubborn buildup with controlled, hands-free movement. Limitation: The magnetic grip may be less effective on very thick tanks or unusual glass thickness beyond stated range.
Mag-Float Medium Acrylic Algae Scraper
The Mag-Float Medium is recommended for acrylic tanks up to 125 gallons with surface thickness up to 3/8″. It emphasizes a floating design for easy retrieval and minimal risk of dropping the tool into the tank. Best for larger acrylic displays where reach and buoyancy matter; choose this if you need reliable floatation and surface-cleaning capability.
fishkeeper Magnetic Glass Cleaner Brush
Fishkeeper provides a strong magnetic pull with two detachable blades: a stainless steel blade for glass and a plastic blade for acrylic. It is designed for tanks up to 0.2 inches thick and includes automatic floating behavior after cleaning. Best for tank owners who want a dual-blade tool and a robust magnet; utilize the stainless blade for tough algae, but avoid using it on delicate acrylic if deep scratching is a concern.
Buying Guide
What to consider when choosing an acrylic aquarium magnet cleaner
- Tank material and thickness: Acrylic tanks benefit from magnets designed specifically for acrylic or dual-purpose tools with soft pads to avoid scratching. Check the maximum thickness the magnet can handle.
- Magnet strength and safety: Strong magnets save effort but can damage delicate equipment if misused. Look for tools with safety features and clear instructions on compatible tank materials and thicknesses.
- Scrubbing vs scraping: Some tools combine both scrubbers and scrapers; others separate functions. Decide if you need edge-to-edge cleaning, corner reach, or flat-panel scrubbing.
- Floating design and retrieval: Floating tools reduce loss risk. Consider whether a tool floats automatically or requires manual repositioning after cleaning.
- Maintenance and blades: Tools with detachable blades offer versatility—stainless steel for glass and plastic for acrylic. Assess ease of blade replacement and cleaning.
- Tank size and space: For small tanks, compact models are ideal; for larger aquariums, choose higher-strength magnets and longer handles.
- Ease of use: A user-friendly tool with intuitive movement and reliable attachment reduces the chance of dropping the tool into the tank.
Frequently Asked Questions
- What is the difference between a magnet cleaner for glass vs acrylic?
Answer: Acrylic-specific tools typically have softer pads and non-scratch materials, while glass tools may use tougher blades; some models are designed for both materials with interchangeable blades. - Can I use any magnet cleaner on a shallow tank?
Answer: Yes, but ensure the magnet strength is appropriate for the tank’s thickness to avoid detachment or insufficient cleaning power. - Should I use the stainless blade on acrylic tanks?
Answer: Avoid using hard blades on acrylic if the kit doesn’t explicitly support it; use the plastic or soft pad option to prevent scratching. - What maintenance does a magnetic cleaner require?
Answer: Rinse pads after use, clean residue from blades, and periodically inspect magnets for alignment and ease of movement. - Is floating a necessary feature?
Answer: Floating helps prevent loss and makes retrieval easier, especially for beginners or busy hobbyists. - How do I choose the right size for my tank?
Answer: Match the cleaner’s recommended tank size or maximum thickness to your aquarium’s dimensions; larger tanks may require stronger magnets and longer reach.
