One thing worth knowing

This is rated for glass up to 6mm — if your tank has thicker glass than that, the magnets may not hold together strongly enough to work, so check your tank's glass thickness before buying.

Why we chose it

Not getting your arm wet every time algae builds up is worth the small cost on its own. The magnet doing both scrubbing and polishing in one pass also means one product instead of two.

Specifications

Brand: Supa

Full description

Cleaning algae off the inside of a tank usually means an arm in cold water up to the elbow, which is the whole reason magnetic cleaners exist. Supa's Algae Magnet cleans the glass from outside the tank instead.

A strong magnet on the outside holds an abrasive cleaning pad in position on the inside of the glass; move the outside magnet and the inside pad follows, scrubbing algae off as it goes, while the outer felt pad polishes the glass at the same time. It's rated for aquarium glass up to 6mm thick.

Small size: 5cm (W) x 2.5cm (L) x 3.7cm (H)
Abrasive inner pad, soft felt outer pad
Suitable for aquarium glass up to 6mm thick
Clean under warm water after use

One thing worth knowing. This is rated for glass up to 6mm — if your tank has thicker glass than that, the magnets may not hold together strongly enough to work, so check your tank's glass thickness before buying.

Who it's for: aquarium owners who want to clean algae off the inside of the glass without putting a hand in the water, on a tank with glass 6mm thick or less.
