I am having major algae problems, lol. Too much coraline growth. Can somebody come take some of this off my hands.

Ok, enough with the bragging already.

Today I spent atleast 30 minutes scraping this stuff off the glass, I use an old credit card. Is there an easier way to remove the coraline overgrowth? I have a glass aquarium. Would it be alright if I use a razor? Yes, I know the razor is metal and we don't like adding metals to our tanks (in any way).

I am thinking that the razor will expedite the removal and due to the short period of time the razor will be submerged, it wouldn't cause that many problems. Any opinions?
