Valonia doesn't compete well for nutrients in the presence of a good quantity of macroalgae. So a refugium would be a good step. I've had valonia at times, and from my experience they are indicative of water quality. When it has popped up in my systems, it has always simply gone away of its' own accord after catching up on tank maintenance. I would tweezer it before adding a crab. As the posts here indicate, your results will be something less than guaranteed.

I have been using emeralds - I do ask for females because I heard that males are a little more voracious and can start eating the wrong thing.

How can you tell the difference between male and female?

I am told that a Foxface Rabbitfish will eat Valonia. There are reports that if not kept well-fed, it will nip on corals. It can also grow relatively large.
