Kill the green stuff

[squidward]

So i have a 75 fowler Lately i have been getting alot of green algae on my glass and my mag scrubber wont get it off any. Suggestions

If it won't wipe off, it's coraline algae. Used a razor blade or the scraper attachment for the mag float.

If the tang leaves the algae alone it is probably coraline algae, break out the razor blade.
