So I am having a problem with bubble algae. Of course its mainly on one of my main bottom rocks which cannot be removed. The front is covered in these things. What is best way to remove them? I have heard that popping them will spread it. I was wondering if that is true? My thought that some people say to get emerald crabs and they will eat it. Well if they eat it I would think it would pop in the process of them eating it. Why would it not spread that way?
Anyway I have a couple emeralds who dont touch the stuff. They eat everything except the bubble.
