Mag-Float Large Plus Acrylic Aquarium Algae Cleaner with Scraper, Floating Magnet

Mag-Float Large Plus is a floating magnetic aquarium cleaner with a scraper, designed to remove algae from aquarium surfaces while keeping your hands out of the water; it is recommended for acrylic tanks of 125 gallons (473 L) and up, with surface thickness up to 3/4 in (1.9 cm).

• Move the outer felt magnet to guide the inner scrubber across aquarium surfaces — clean without reaching into the tank.
• Rare-earth neodymium magnets connect the cleaner’s two halves.
• The inner scrubber floats when detached, ready to retrieve from the water’s surface.
• Toxic-free ABS plastic and a pad that stays free of sand and gravel help prevent scratches.
• Works in freshwater and saltwater aquariums, on glass or acrylic.
• Large Plus is recommended for acrylic aquariums from 125 gallons, with surface thickness up to 3/4 in.

Algae on aquarium surfaces can be awkward to reach without putting a hand into the tank. Mag-Float is made for routine tank cleaning, including hard-to-reach spots, while helping you avoid disturbing corals or decorations. Keeping your hands outside the aquarium also helps avoid introducing soaps or skin toxins into the fish’s environment.

How does the Mag-Float cleaner remove algae?

Press the outer half against the outside of the aquarium, and the magnet draws it together with the inner scrubber. Moving the outer felt magnet makes the inner cleaning pad follow along the surface.

• When cleaning is finished, detach the outer magnet; the inner scrubber rises to the surface.
• The floating scrubber can rest there until the next cleaning.
• The cleaner can remain attached to the aquarium when not in use, including between cleaning sessions.

What aquarium size and surface thickness suit Large Plus?

For acrylic aquariums, Mag-Float Large Plus is recommended for tanks sized 125 gallons and up, with a surface thickness no greater than 3/4 in (1.9 cm). Compare your aquarium’s surface thickness with this limit when choosing the cleaner.

• The stated tank-size recommendation applies to acrylic aquariums.
• The cleaner is also functional in freshwater and saltwater setups.

How does it help protect the aquarium and its contents?

The cleaning pad stays free of sand and gravel, helping prevent unsightly scratches to aquarium glass or acrylic. Its magnetic cleaning action lets you work from outside the tank instead of reaching among fish, corals, or decorations.

• Keeping hands out of the water helps avoid introducing soaps or skin toxins.
• The outer felt side is moved by hand while the inner pad follows inside the aquarium.
• Rare-earth neodymium magnets are used and are designed not to lose strength over time.

Mag-Float Large Plus suits aquarium owners who want to clean algae from tank surfaces without putting their hands in the water, including owners of compatible acrylic tanks and freshwater or saltwater aquariums. Its floating inner scrubber and outside-operated magnetic design make it a practical fit for surface cleaning around aquarium contents.
