The best aquarium magnet cleaner depends first on your tank’s pane material and thickness. For a general glass or acrylic aquarium with panes up to 12 mm thick, the Flipper Standard is a versatile specification-based pick: it switches between scrubbing and scraping and floats when disconnected. Choose a Mag-Float for straightforward routine cleaning across a broad range of thickness classes, or consider TUNZE for unusually thick glass and specialist reef maintenance. These are recommendations based on manufacturer specifications, not independent head-to-head testing.
Which aquarium magnet cleaner should you choose?
| Cleaner | Best fit | Documented compatibility and limits | Useful feature |
|---|---|---|---|
| Flipper Standard | One cleaner for routine scrubbing and scraping | Glass and acrylic tanks up to 1/2 inch (12 mm), according to Flipper Aquarium Products’ current product page (source). | Rotating handle switches between scrubber and scraper modes; floating design aids retrieval if it disconnects. |
| Mag-Float | Simple daily cleaning with a model selected for the pane | Glass and acrylic-compatible models are listed separately. Glass models cover thickness classes up to 2 inches, depending on model; scraper attachments are model-specific, according to Mag-Float’s product pages (glass models; acrylic models). | Multiple thickness and tank-size classes; the manufacturer says the inner magnet is easy to retrieve. |
| TUNZE Power Magnet | Thicker glass or specialist cleaning needs | Power Magnet models are specified for glass from 6 to 55 mm (1/4 to 2 inches) in TUNZE catalog material (source). | Broad documented glass-thickness range. TUNZE Care Magnet literature describes a separate range around 3–25 mm and floats that bring the detached inner magnet to the surface (source). |
| Flipper Nano | Small, thinner-pane aquariums | Designed for tanks up to 1/4 inch (6 mm) or about 25 gallons, per Flipper Aquarium Products’ current product page (source). | Stainless-steel blade for glass; manufacturer recommends blade replacement every 3–6 months. |
Check pane material and thickness before buying
Measure the aquarium pane itself rather than choosing by the tank’s gallon capacity alone. Capacity labels are useful for narrowing options, but the magnet must be rated for the actual glass thickness. For acrylic, select a model explicitly identified as acrylic-compatible; a glass model or blade attachment should not be assumed safe for acrylic.
Mag-Float glass size classes
Mag-Float’s listed glass models pair capacity classes with maximum glass thickness: Float-Small is listed for tanks up to 30 gallons and 3/16-inch glass; Float-Medium, up to 125 gallons and 3/8-inch glass; and Float-Large, up to 350 gallons and 5/8-inch glass. Larger models are listed for glass thicknesses up to 3/4, 1 1/4, and 2 inches, depending on model. These are manufacturer specifications, not independent measurements. See the Mag-Float glass product page.
Mag-Float acrylic models
Mag-Float lists acrylic-compatible cleaners in separate Small, Medium, and Large capacity classes. Check the specific acrylic model’s pane-thickness rating before ordering, and do not assume that a glass model with a similar name or capacity is interchangeable. The manufacturer also notes that scraper attachments are model-specific. See the Mag-Float acrylic product listings.

Flipper and TUNZE thickness ranges
The Flipper Standard is specified for glass and acrylic up to 12 mm (1/2 inch); the Nano is for panes up to 6 mm (1/4 inch). TUNZE’s catalog distinguishes Power Magnet models, specified for 6–55 mm glass, from Care Magnet models described for roughly 3–25 mm glass. Check the exact model and its instructions, especially where material compatibility is not stated for the particular model.
Match the cleaning surface to the algae
Soft film algae
For routine soft algae film, a scrubber pad is generally the relevant tool. A scrubber-only cleaner keeps the setup simple, while a dual-mode cleaner offers a scraper when needed. Keep grit out of the pad before moving it across the pane.

Hard, crusty deposits
Hard deposits may call for a scraper blade, but blade compatibility depends on the aquarium material and the exact cleaner model. Flipper Standard rotates from scrubber to scraper mode. Flipper Nano’s product page specifies a stainless-steel blade for glass; do not infer acrylic suitability from that specification. Use blades only on surfaces and models permitted by the manufacturer.
How to use a magnetic aquarium cleaner without scratching the pane
- Confirm the cleaner matches the pane. Verify the aquarium is glass or acrylic and check its thickness against the exact model’s specification.
- Inspect the pad before each pass. Remove visible sand or grit; particles trapped between the pad and pane can scratch either glass or acrylic.
- Use the appropriate cleaning surface. Start with the scrubber for soft film. Engage a scraper blade only if the manufacturer permits it for that pane material and model.
- Move the cleaner carefully. If you feel resistance or suspect debris has entered the pad, stop and inspect it rather than dragging it across the pane.
- Retrieve a detached inner piece as directed. Floating designs can make recovery easier: Flipper Standard floats, and TUNZE Care Magnet literature describes floats that bring the inner magnet to the surface.
Manufacturer specifications do not establish comparative scratch performance. In particular, the cited product pages are not independent scratch tests, so careful pad inspection and following model-specific instructions remain important.

When are replacement blades or parts needed?
Flipper recommends replacing the Nano’s blade every 3–6 months to maintain algae scraping performance; that interval is the manufacturer’s guidance, not a universal replacement schedule for every cleaner. Mag-Float’s scraper attachments are model-specific, so confirm the correct part for the exact cleaner before fitting one. For other models, follow the manufacturer’s replacement and maintenance instructions.
