Here is a very interesting type of algae scraper for your aquarium which is said to give you “better cleaning results” with a unique blade design that “removes algae in sheets rather than in a cloud allowing easier removal and is tough enough to remove the most stubborn algae, even coralline algae.” It is also easier to use with a “hi-tech polymer blade that cleans without scratching and prevents grit getting stuck in cleaning surfaces, and if the magnetic coupling is released it floats.” Which reminds us of the mag float that is very popular. This design works on both flat sided or spherical aquariums made of acrylic or glass, although we wonder how well it would do for both glass and acrylic tanks because most alage removal devices use a strong type of magnet for glass. This green “UFO” retails for about $16.
