Removing Coraline

[greenmonkey51]

Anyone got any sure ways to remove coraline algae. I moved my 75g to my 125g and emptied the 75g. I need to scrape off the coraline now. I know that a lot of people use razor blades on scrapers, but was wondering if anyone had any ways to soften the coraline before I scrape it.

If the tank is empty, lay it on it's side and pour in some white vinegar. After 1/2 hour, it scrapes out much easier. Do it to each side that needs it.

And you can use paper towels soak in vinegar if you what to do more than on side at a time.
