How to get rid of Valonea algae?

[Delphinus]

I've never had luck with emeralds either. Seems to me it's 50/50 .. They'll either take to valonia, and then if so they'll eat darn near all of it ... or they won't touch the stuff.

I got lucky, my Red Sea sailfin tang eats the stuff.

I might try the boiling hot water trick that's been described for getting rid of bryopsis (which I just tried BTW, and man that's slick way to get rid of those stubborn patches!) .. You just turn your pumps off for a few minutes, then take a syringe or something and just slowly release the scalind hot water onto the errant algae ... and then in a couple days, it's gone.
