Is might be some kind of agressive coraline , i have a green kind that will grow up the stalks of the zoas it grows with until it forms a long tube and finaly covers the head . Ive tried scrubbing it off , but it wont budge.

I have (three types of red) & blue & green coraline algae.....this is not like coraline.....although the pictures are deceving as it looks like coraline. Its really fuzzy like mold and dark grey to blackish......its not hard looking.....its quite fuzzy looking.
