Best Mag Float Aquarium Algae Scrapers in 2026

You are staring through the front pane of your aquarium only to realize a stubborn layer of green algae has completely obscured your view of your fish. Instead of reaching into the water and risking a mess, you can simply grab the Aqueon Algae Cleaning Magnet and glide it along the exterior. The curved pad design is a massive advantage here, as it transitions smoothly between flat panels and curved corners without losing suction. I particularly like the thoughtful engineering of the weighted scrubber. It stays put during use and, more importantly, sinks straight to the bottom if it ever detaches from the magnet. This prevents the common headache of chasing a floating piece of equipment through the water column. It works reliably on both glass and acrylic tanks, making it a versatile staple for any hobbyist.

The coarse interior pad tackles stubborn algae while the soft exterior pad polishes the outside for a streak-free finish. I especially appreciated the concave, non-slip grip which makes maneuvering through tight corners surprisingly easy without getting your hands soaked. Best of all, if the connection ever breaks, the pieces float rather than sinking into your substrate, making retrieval a total breeze.
