Recently, this pink/purple foam thing started overgrowing zoas in my zoa garden. What is it? What eats it or removes it aside from manual removal? Here are photos of it on zoa frags I removed to clean.
I'm thinking it is a sponge. I have been removing the impacted rocks and frags and gently brushing it off them with a toothbrush. But I would prefer a safe method that is not so time-consuming. Suggestions? Thanks!
