I've been battling the corralline on my acrylic tank now for almost 3 years to the point I'm ready to tear it down and buy a glass tank. I've tried scrapers and credit cards and both worked, but with a 225 it takes a forever and I always found my hand was cramping terribly. I was doing some reading on a thread from 2010 and it was suggested to use a piece of acrylic that is softer than tank acrylic, which I tried and it worked great. I don't have any visible scratches (test this somewhere other than the front first) and even the tough stuff came off with a little effort. Just thought I'd pass on the tip for anyone that has struggled like me!
