Gulfstream Tropical Mag-Float Glass Aquarium Cleaner, Large Floating Algae Brush

Gulfstream Tropical AGU350LG Mag-Float is a large magnetic aquarium cleaner for removing algae from glass, with a buoyant design that stays afloat during use.

• Made for glass aquariums — targets algae on the glass.
• Buoyant design — remains afloat rather than sinking.
• Guides around corners — helps maneuver the cleaner along aquarium glass.
• Strong attracting magnets — provide the cleaning force to remove algae.
• Brush stays free of sand or gravel — helps prevent scratching.

Cleaning algae from aquarium glass calls for a tool that can be moved across the surface while remaining easy to guide. The Mag-Float brings together magnetic cleaning and buoyancy for that task. Its floating action is useful when steering around corners, while the brush design addresses contact with sand or gravel during cleaning. This is the Large model, identified as AGU350LG, for shoppers looking for a magnetic cleaner specifically made for glass aquariums.

What is the Mag-Float glass aquarium cleaner designed to do?

It is designed to remove algae from aquarium glass using strong attracting magnets. The magnetic cleaning action provides the force for algae removal, and the product is intended for glass rather than a general-purpose household surface. Its floating design supports maneuvering during the cleaning task.

• Product type: magnetic aquarium cleaner.
• Target surface: aquarium glass.
• Cleaning task: algae removal.

Will it sink while I guide it around aquarium corners?

No: the cleaner is buoyant and floats, making it easier to operate and guide around corners without sinking. That buoyancy is the defining practical difference of this Mag-Float cleaner; it keeps the tool afloat as you steer it through the cleaning task, rather than allowing it to sink out of reach.

• Buoyancy supports handling while cleaning.
• Corner guidance is part of its intended use.

How does the brush design help protect aquarium glass?

The brush stays free of sand or gravel, helping prevent scratching while you clean. This detail is relevant when cleaning an aquarium where loose substrate may be present: the brush design is intended to keep those particles from collecting on it and scratching the glass. The product combines that brush feature with magnetic algae removal for glass aquariums.

• Brush feature: stays free of sand or gravel.
• Intended benefit: helps prevent scratching during cleaning.

The Gulfstream Tropical AGU350LG Mag-Float suits aquarium owners who want a magnetic tool for algae on glass and value a cleaner that floats as it is guided around corners. Its glass-focused use, buoyancy, and brush design make it a practical fit for that cleaning task.
