What is the best way to remove coraline algae on acrylic tank?

Mag float makes them for acrylic tanks too.

Seem like mag float makes slight scratches.
Do you know any creatures doing a good job eating coraline algae?

Urchins eat coralline algae, but not enough to keep the glass totally clean. I find most tools designed to clean acrylic tanks suck at their job. The Kent scrapers with the plastic blades suck. I tried one on my glass tank and the plastic blade doesn't seem to be flat enough because it won't even clear the soft film off the glass in a clean sweep. I have the long handled Kent scraper, maybe with a short handled one a person could apply more pressure and have it work better...?

CDN Tire had a ceramic scraper...it was for stove tops
