Flipper FLOAT Standard is our best aquarium magnetic algae cleaner for its reversible scrubber and scraper and its choice of blades for glass or acrylic. We compared three floating designs using their documented specifications, with attention to pane thickness, cleaning surfaces and the compromises that matter in a stocked tank.

Flipper FLOAT Standard
Flipper FLOAT Standard
The FLOAT Standard combines a scrubbing pad and a scraper on opposite faces. Rotate the outer handle to flip the inner piece, so you can move from a soft film to a more persistent deposit without taking the assembly apart. Flipper specifies glass and acrylic panes up to 12 mm thick and includes a stainless-steel blade for glass and an ABS blade for acrylic. Its inner section floats when separated, and the manufacturer describes three contact points on the blade side to leave a gap behind the edge. This versatility earns our overall pick for owners who want both cleaning actions in one tool. The limitation is that the correct blade must be fitted for the material; trapped grit can still scratch, and the relatively substantial body needs room between decorations and the pane.
Pros
- Rotating handle changes between pad and scraper
- Includes separate steel and ABS blades for their intended surfaces
- Floating inner section is easier to recover
Cons
- Blade must be matched to the pane material
- Larger body needs clearance behind decorations
Mag-Float Glass Medium
Mag-Float Glass Medium
The Glass Medium is a straightforward floating magnet for people who primarily wipe the viewing panes of a glass aquarium. The maker rates this model for glass up to 3/8 inch thick and suggests aquariums up to 125 gallons; pane thickness is the more useful measurement when choosing magnetic strength. The stated dimensions are 4 by 1 3/8 by 1 inch, and the inside piece rises if the two halves separate. Its focus on a replaceable cleaning pad makes it our routine glass choice rather than a two-sided scraper. An attachment for harder deposits is sold separately, so do not assume a blade comes in the box. This particular glass version is not the acrylic model, and it cannot substitute for a suitable tool on an acrylic wall.
Pros
- Medium glass version is specified for panes up to 3/8 inch
- Floating inside half avoids fishing a loose pad from the bottom
- Replacement pad and felt are available for the medium glass model
Cons
- Scraper attachment is an extra purchase
- Glass-specific pad is not the separate acrylic version
Jasonwell Floating M
Jasonwell Floating M
Jasonwell's M is a paired magnetic brush with a felt-lined external handle and a floating inner cleaner. The outside piece guides the brush through the wall, and a detached inside half can be retrieved from the surface rather than the gravel. The listing identifies the M size and says it is for ordinary glass, explicitly excluding acrylic and low-iron glass. That makes it a useful simple-brush option if your tank material is known and you prefer wiping to changing blades. The seller says stronger magnets correspond to larger sizes, but does not establish a dependable maximum thickness for this exact M listing. Confirm fit with the seller before ordering rather than assuming that a particular tank volume guarantees a secure grip.
Pros
- Felt lines the external handle that moves across the pane
- The M brush floats if the magnets separate
- Simple paired brush needs no blade change for routine wiping
Cons
- Listing excludes acrylic and low-iron glass
- Exact maximum pane thickness is not stated for this M listing
How to choose and clean safely
Measure the wall, not just the tank's capacity. A thick panel can weaken the connection even on a modest-sized aquarium. Flipper publishes a 12 mm limit for the Standard, while Mag-Float specifies 3/8 inch for its Medium glass model. Jasonwell's selected listing does not give an equivalent reliable limit, so ask before committing. Neither magnet strength nor a larger size makes an unsuitable cleaning surface safe for acrylic.
Inspect both contact surfaces before use. A grain of sand or a hard shell fragment trapped under a pad can score a pane, even when the product floats. Work slowly above the substrate, stop if the inner part detaches, and rinse away particles with clean water. Avoid sweeping a blade across silicone joins or pressing it into a corner; a suitable hand tool is easier to control there. These cleaners remove visible film from the wall but do not replace normal water changes or address the cause of persistent algae growth.
Before choosing, consider how much room your aquascape leaves behind the glass. A magnetic cleaner cannot pass through a rock or filter housing, and a larger body needs a wider gap. If access is tight, measure that clearance as well as the pane thickness. Keep a separate suitable hand tool for the areas the magnet cannot reach, rather than forcing either half past an obstacle.
FAQ
Can one magnetic cleaner work on glass and acrylic?
Some can, but only when the manufacturer specifies both materials and supplies or recommends the appropriate contact surface. Flipper FLOAT Standard includes different blades for each. The selected Mag-Float and Jasonwell are glass versions. Acrylic scratches readily, so do not treat a glass pad or metal blade as interchangeable with an acrylic-safe one.
What happens if the inner magnet comes loose?
The inner sections of all three selected cleaners float, making retrieval at the water surface easier than searching in the substrate. Guide the outer magnet back gently and check the cleaning surface before continuing. Floating does not guarantee that a pad is free of grit if it has already touched sand or debris.
Does a larger aquarium need a stronger magnet?
The relevant measurement is the thickness of the pane the magnets must grip through, not the number of gallons alone. Compare it with the chosen model's documented limit and confirm material compatibility as well. If the listing does not give an exact thickness, as with the selected Jasonwell M, ask the seller before ordering.
