Mag-Float Medium Acrylic Aquarium Algae Scraper with Floating Magnetic Cleaner

Mag-Float Medium is a floating magnetic aquarium cleaner designed to remove algae from tank surfaces while keeping your hands out of the water; it is recommended for acrylic aquariums up to 125 gallons (473 L) with surfaces 3/8 in (9.5 mm) thick.

• Floating inner scrubber — rises to the water’s surface when detached for easy retrieval.
• Rare-earth neodymium magnets — keep the two cleaning halves connected through the aquarium surface.
• Freshwater and saltwater compatibility — clean either type of aquarium with the same tool.
• Cleaning pad stays free of sand and gravel — helps prevent unsightly surface scratches.
• Toxic-free ABS plastic body — can remain attached to the aquarium 24/7.

Cleaning algae from an aquarium can mean reaching into the water, where hands may disturb corals or decorations and introduce skin residue or soap. Mag-Float Medium lets you move the exterior magnet instead, making routine glass cleaning simpler and helping you reach spots that are harder to access by hand. Its floating design also keeps the inner scrubber available at the surface between cleaning sessions.

How does Mag-Float Medium clean the aquarium?

Move the outer felt magnet along the outside of the tank and the magnetic connection guides the inner scrubber across the inside surface. To start, press the outer half against the aquarium so the magnets connect; when you finish, detach the outer magnet and the inner half floats to the top. The cleaner is designed to reduce hands-on effort during aquarium maintenance.

• Leave the inner scrubber floating on the water when it is not in use.
• Use the exterior half to guide the interior scrubber across the surface.

What aquarium size and water types suit the Medium cleaner?

The Medium size is recommended for acrylic aquariums up to 125 gallons (473 L) with a surface thickness of 3/8 in (9.5 mm). Mag-Float works in both freshwater and saltwater aquariums, and the cleaner is designed for aquarium glass and acrylic surfaces. For acrylic tanks, compare the capacity and surface thickness with these stated limits.

• Suitable for freshwater aquariums.
• Suitable for saltwater and marine reef aquariums.

How does its floating design help protect the aquarium?

Because you guide the cleaner from outside the tank, your hand does not need to enter the aquarium during cleaning. This helps avoid disturbing tank contents such as corals and decorations, and helps reduce the chance of introducing toxins or soaps from your skin. The pad remains free of sand and gravel, which helps prevent scratches on the aquarium surface.

• The inner scrubber returns to the surface when the magnetic halves separate.
• The ABS plastic body is made to remain attached between cleaning sessions.
• The rare-earth neodymium magnets are designed not to lose strength over time.

Mag-Float Medium suits aquarium owners who want to clean algae from glass or acrylic without putting a hand into the tank, including freshwater and saltwater keepers. For acrylic aquariums, its recommended fit is up to 125 gallons (473 L) with a surface thickness of 3/8 in (9.5 mm), and its floating inner scrubber is ready at the surface after use.
