I've always used a straight razor-- and when held at the right angle they really dont cause damage to the glass at all, especially when they are kept clean and free of rust. The only thing to watch is when u are scraping around or close to the silicon adhesion for ur tank pieces-- Be careful......lol..... leaks baaaad!
The other thing ive used are those "algae scrubber" pad things-- take a little more elbow grease-- esp. for coralline, but y'know...
just my 2 cents
