Review on Efficient 2-In-1 Magnetic Fish Tank Cleaner With Non-Slip Design And Scratch-Free Blades by Jason Hill

I've used several algae scrapers and this actually works! I've been dealing with green spot algae and the handled scrapers haven't been up to the task. The edge of a credit card technique works to some extent but is a major pain. I didn't really expect this tool's blade to work considering the other fails, but it really did! The size seems just right. I have found those with a larger footprint really don't speed the task up; I think spreading the surface over a larger area actually results in less pressure and less cleaning. Very happy with this purchase so far. My tank hasn't looked this good for quite awhile.
