Why we recommend the Mag-Float Floating Aquarium Glass Cleaner
Algae on the front glass is the chore that never ends, and the Mag-Float makes it about as painless as it gets. You place the scrubbing half inside the tank, hold the handle half against the outside, and glide it across the pane, lifting algae film without ever putting your hand in the water. It is the kind of simple, well-executed tool that quickly becomes part of your daily walk past the tank.
The signature feature is right in the name. If the magnets separate, the inner piece floats back to the surface instead of dropping into the substrate, which spares you the annoyance of reaching to the bottom and the risk of dragging grit across the glass. The magnets are sized to different glass thicknesses, so choosing the right model matters for grip and performance, and the design is durable with very little that can fail. It handles both freshwater and saltwater duty, making it a versatile addition to any maintenance kit.
Who it’s for
This cleaner is ideal for any glass-tank keeper who wants to stay on top of algae without the hassle of wet sleeves or scrapers. It suits both freshwater and reef hobbyists and shines for quick, frequent touch-ups. If you keep an acrylic tank you will need the acrylic-safe version, and very stubborn coralline deposits may still call for a dedicated blade, but for everyday glass cleaning it is hard to beat.
The Bottom Line
The Mag-Float earns its loyal following by making a tedious chore quick and dry, and the floating design spares you from fishing a magnet out of the gravel. Match the size to your glass and it becomes a maintenance tool you reach for constantly.

Frequently Asked Questions
Will it scratch my glass?
Only if it picks up a sand grain. Keep it away from the substrate and lift it out to inspect the pad if it nears the bottom.
How do I pick the right size?
Match the model to your glass thickness. Too small and the magnets will not hold securely through the pane.
Does it work on saltwater tanks?
Yes, it handles both freshwater and saltwater glass, though heavy coralline may need a blade as well.
Can I use it on an acrylic tank?
Only with the acrylic-safe version, since the standard pad can mar acrylic surfaces.
What happens if the magnets come apart?
The inner half floats to the surface, so you can simply retrieve it rather than digging through the substrate.
