I had a bad case of Valonia outbreak 6 months ago. I bought a couple of emerald crabs and they really attacked the small and medium sized bubbles..they don't really touch the larger ones. I cleaned up the larger ones by popping them with a bbq skewer, pretty much eliminated all of them. People say that popping them will only spread and propogate the algae..but in my experience this was not the case. My bubbles have been controlled and I won't hesitate to pop any larger ones in the future. This is my first hand experience.
