I don't have any scrapings but if you have any growing on any rocks, you can scrape them and let it fall into the water. Make sure your calcium is about 400PPM and your Alk is at higher acceptable levels. I forget those numbers. It makes the coraline grow faster. It also works to smash coraline covered rock pieces and scattering them into the rocks. That worked best for me because the pieces are heavier and tend to grow where they land.
