If you keep an aquarium, you want a reliable magnetic scrubber that cleans inside surfaces without wetting your hands. This guide highlights top magnetic aquarium cleaners ideal for glass and acrylic tanks. They’re chosen for different tank sizes, glass thickness, and user needs. Best for small tanks are compact, lightweight cleaners; best for large or thick glass are extra-strong magnets; better for acrylic are soft pads and dual blades. Read on to compare five strong options and find the right fit for your setup.
| Product | Best For | Glass/Acrylic Compatibility | Notes |
|---|---|---|---|
| Aqueon Small | Smaller tanks, casual upkeep | Glass/Acrylic | Curved pad; easy retrieval |
| Aqueon Medium | Medium tanks, regular cleaning | Glass/Acrylic | Same design as small, scalable |
| AQQA Magnetic Cleaner (M) | Medium-thick glass, dual-sided cleaning | Glass | Floating design; multiple sizes |
| DaToo Mini | Compact, quick daily clean | Glass | Super-strong magnet; efficient |
| fishkeeper Small | Precision cleaning inside corners | Glass/Acrylic | Double-sided; detachable blades |
Aqueon Aquarium Algae Scraper, Small
Best for small tanks and hobbyists seeking a straightforward exterior-cleaning magnet. The magnet allows cleaning from outside the aquarium, while the curved pad handles flat and curved surfaces. The scraper falls straight down if the magnet separates, simplifying retrieval. Suitable for glass or acrylic tanks, especially when space is limited.
Who it’s best for: beginners and hobbyists with small tanks who want a simple, reliable tool. Why selected: compact, easy to operate, and compatible with multiple surfaces. Limitation: powerful cleaning might require careful alignment in tight corners.
Aqueon Aquarium Algae Scraper, Medium
Best for mid-sized tanks requiring a bit more reach without losing control. The magnet lets you clean inside surfaces from outside, and the scrubber’s design ensures it remains attached during use. The curved cleaning pad covers both flat and curved surfaces, improving efficiency on varied tank shapes.
Who it’s best for: hobbyists with medium tanks or slightly thicker glass. Why selected: proven Aqueon design, reliable magnetic connection, versatile cleaning. Caution: avoid rotating too quickly to minimize splashing near delicate aquatic life.
AQQA Magnetic Glass Cleaner, Medium (M)
Best for mid-thickness glass with a dual-sided cleaning approach. AQQA offers a reinforced outer magnet and a double-sided cleaning pad (fabric and mini hooks). The floating design helps you retrieve the cleaner without wetting hands, and different sizes adapt to various tank thicknesses.
Who it’s best for: aquarists with 0.2–0.6 inch glass and a preference for ease-of-retrieval. Why selected: strong magnet, versatile cleaning, floating feature. Limitation: magnet strength varies with glass thickness; choose the correct size for your tank to maximize effectiveness.
DaToo Aquarium Mini Magnetic Scrubber
Best for compact tanks and quick daily cleanups. The DaToo Mini uses a super-strong NdFeB magnet to provide reliable cleaning power in a small package. It features a soft cleaning pad on one side and an abrasive pad on the other, enabling quick removal of dust and stains.
Who it’s best for: owners of small to medium tanks who want fast, no-hassle cleaning. Why selected: compact, strong magnet, dual cleaning surfaces. Caution: ensure the exterior panel and interior substrate are clear of obstructions to avoid scratches.
Aqueon Aquarium Algae Scraper, Large
Best for larger tanks or thicker glass where more reach and stronger cleaning is needed. The mag-net still allows exterior cleaning while the curved pad handles stubborn algae on curved surfaces. The design mirrors the small and medium models for consistency across tank sizes.
Who it’s best for: aquarists with larger setups seeking uniform performance. Why selected: scalable design with a robust magnet and curved cleaning surface. Limitation: larger size may be less comfortable in very small aquariums.
fishkeeper Aquarium Magnetic Glass Cleaner, Small
Best for precision cleaning and lightweight operation in smaller tanks. The cleaner features two detachable blades (stainless steel and plastic) to accommodate glass and acrylic surfaces. The floating design ensures easy retrieval and reduces the chance of losing the tool.
Who it’s best for: tank owners who want flexibility with blade options and quick access. Why selected: robust magnetic hold, dual blades for different surfaces. Caution: blades require directional cleaning to avoid scratching sensitive finishes.
Buying Guide
What to consider when shopping for a magnetic scrubber
- Tank material: Glass vs. acrylic affects blade choice and pad texture. Some models include both interior and exterior cleaning surfaces to accommodate both materials.
- Tank thickness: Magnetic strength should match glass thickness. Heavier tanks need stronger magnets and larger outer magnets.
- Cleaning surfaces: Dual-sided pads (soft fabric and abrasive surfaces) handle algae and mineral deposits differently. Choose based on your tank’s needs.
- Retrieval design: Floating or self-releasing mechanisms help prevent loss when the magnet detaches from the glass.
- Size and reach: Smaller scrapers are easier to maneuver in compact tanks, while larger models cover more surface area in bigger tanks.
- Replaceable blades and pads: Check whether replacement parts are available for long-term maintenance.
Quick comparison at a glance
- Best for small tanks: Aqueon Small
- Best for medium tanks: AQQA M or Aqueon Medium

- Best for acrylic tanks: models with plastic blades (e.g., fishkeeper, DaToo variants)
FAQ
- Can magnetic cleaners scratch glass or acrylic surfaces? A: Use the appropriate blade and pad, and move in a single direction to reduce risk of scratches.
- Will a stronger magnet work for all tank thicknesses? A: No. Magnets are designed for specific thickness ranges; choose the size that matches your tank.
- Do magnetic cleaners require maintenance? A: Yes; rinse pads after use and replace worn pads or blades as needed.
- Are magnetic cleaners safe for fish? A: They are low-risk when used as directed; avoid spraying cleaners or chemicals near the tank.
- Which model is best for beginners? A: Compact, lightweight options with simple retrieval mechanisms are recommended for first-time users.
- Can I use the same cleaner on both glass and acrylic? A: Some models include dual blades or pads compatible with both surfaces, but verify compatibility before use.
