Well, after trying many a scraper, I'm in love. I've always had issues with getting coraline off my glass. I tried Kent scrapers, because of rock work I couldn't get in some areas. I tried the Mag Flip scrubber scrapper but I always felt the magnet wasn't strong enough. So I tried this little thingy

In about 2 minutes I was able to scrape every last residue off 3 sides of my 77. Obviously care must still be taken to not scratch your glass, but I can now see in my tank again.
