Choose a magnetic aquarium cleaner by tank material and measured pane thickness first; tank volume alone is not enough. Manufacturer specifications support different Mag-Float models for glass and acrylic across a range of thicknesses, and the Tunze Care Magnet nano for 6–10 mm glass. The reviewed sources do not establish a hands-on or comparative performance winner, so these are best-fit options based on documented compatibility.
Quick comparison
| Use case | Documented option | Manufacturer-listed fit | Important note |
|---|---|---|---|
| Small glass aquarium | Mag-Float Nano, item 00022 | Up to 30 gallons or 3/16 inch (5 mm) glass | Measure the pane; “nano” does not identify one shared thickness range. |
| Small acrylic aquarium | Mag-Float Acrylic Mini | Up to 10 gallons and 3/16 inch | Choose the acrylic-specific model, not a glass model. |
| Nano cleaner for thicker glass | Tunze Care Magnet nano, 0220.010 | 6–10 mm glass | Tunze expressly does not recommend Care Magnet for acrylic. |
| Glass or acrylic in a broad thickness range | Matching Mag-Float model for the material | Glass and acrylic lineups have model-specific limits from 3/16 inch through 1 1/4 inch; Professional models are listed for 1 1/2–2 inch surfaces | Confirm the exact model and material before buying. |
These recommendations reflect manufacturer product specifications, not independent testing. The makers’ pages reviewed do not establish which cleaner is fastest, safest, or most durable in every aquarium.
Best glass nano options: Mag-Float Nano and Tunze Care Magnet nano
“Nano” is not a common thickness standard. Mag-Float lists its glass Nano, item 00022, for small aquariums up to 30 gallons or glass up to 3/16 inch (5 mm). Tunze lists its Care Magnet nano, model 0220.010, for 6–10 mm glass. Measure the glass and compare it with the exact model specification rather than choosing by the product name or tank volume.
Tunze says the Care Magnet nano includes a replacement plastic blade and colored end caps; its blade width is 45 mm. Tunze also warns that adhering sand or dust can scratch glass and advises checking that the cleaner’s contact surfaces and the glass are free of contaminants before use.

Best acrylic route: choose a Mag-Float acrylic model
Mag-Float publishes a separate acrylic product lineup. Its acrylic Mini is listed for aquariums up to 10 gallons and panes up to 3/16 inch. Other acrylic models have their own thickness limits, so verify the exact model rather than assuming a glass-branded cleaner is suitable for acrylic.
Tunze expressly does not recommend using the Care Magnet on acrylic. Do not choose it for an acrylic aquarium; use a cleaner that its manufacturer specifically identifies for acrylic.
Options for thick glass or acrylic
Mag-Float lists separate glass and acrylic models for thicker panels. In both lineups, the listed ranges include X-Large models through 1 1/4 inch and Professional models for 1 1/2–2 inch surfaces. These are distinct model categories, not a general rating for every large cleaner.

How to choose a magnetic aquarium cleaner
1. Identify the tank material
First determine whether the aquarium panel is glass or acrylic. Mag-Float lists distinct product lines for the two materials, and the specific model’s labeling matters. Tunze says its Care Magnet is not recommended for acrylic.
2. Measure the pane
Check the aquarium manufacturer’s specifications or measure the panel. A gallon recommendation is a secondary fit detail, not a substitute for the cleaner’s stated thickness range. For example, Mag-Float Nano is listed for up to 3/16 inch (5 mm) glass, while Tunze Care Magnet nano is listed for 6–10 mm glass.

Is Tunze Care Magnet nano suitable for acrylic?
No. Tunze expressly does not recommend Care Magnet for acrylic. Use a cleaner specifically identified by its manufacturer for acrylic.
Why should I measure the aquarium pane instead of relying on gallons?
Manufacturers publish thickness limits by cleaner model. Tank volume does not establish whether the magnet is compatible with the panel thickness.
Can particles scratch aquarium glass while using a magnetic cleaner?
Yes. Tunze warns that adhering sand or dust can scratch glass and advises checking the contact surfaces and pane for contaminants before use.
What magnetic cleaner works on very thick panels?
Mag-Float lists X-Large models through 1 1/4 inch and Professional models for 1 1/2–2 inch surfaces in both its glass and acrylic lineups. Verify the exact model and material rating before buying.
The bottom line
Measure the pane and select a cleaner specifically listed for the aquarium material. For small glass tanks, Mag-Float Nano is listed up to 3/16 inch (5 mm), while Tunze Care Magnet nano is listed for 6–10 mm glass; acrylic owners should choose a Mag-Float acrylic model or another explicitly acrylic-rated cleaner.
