I had picked up bubble algae a couple months ago from frags I had picked up (no names mentioned), and was then very vigilant in plucking these emerald gems out of the tank every time I say them. About 2-3 weeks ago I thought I had them beat. Today I look in the tank and see this beast sticking its head out of the clove polyps. What a monster! What is the secret of finally getting rid of this stuff?
