Best way to remove coralline algae?

It took me nearly an hour to get all the coralline algae off of my powerheads today. I pre-soaked them for around 30 minutes in vinegar and scrubbed and scraped away. There's got a be a better way and I'm assuming CLR isn't exactly reef safe. I'd also like to remove it from the overflows on my tank too, which are internal. Any tips and tricks? I don't want to get an urchin as I do like the algae, I just prefer to keep it on the rocks only.

I don't have any tips or tricks, just lots of razor blades.

Use a Kent scraper. Razor blades are hard to manage when scraping acrylic and often cut it as you scrape.

I bought a used tank off a fellow member and the overflow box on it was covered in coraline as well as parts of the glass.
I just used this thing,

We have a few of them laying around the house and they are good at other cleaning job like when let a pot boil over and burn milk product or plastic to the glass stove top... (oops) so I thought I'd give it a try on the tank. Little water, little strength behind it and it all came out nice and shiny. But its not exaclty something you can run to the grocery store and buy, so I dont think my post is all that helpful... lol.

Tried and true - vinegar / scrapping
