How to get rid of Valonea algae?

[Stones]

Just wondering what methods have worked or not worked for getting this algae out of their tanks. I've heard urchins, emeralds, foxface, sailfin tang and yellow tangs can help. I haven't got too much of it in my tank as I manually remove it if I can but there are always a dozen or so bubbles that grow in places that are impossible to reach without dismantling the entire rockscape. Any ideas would be greatly appreciated.
