Alage Identification

[WVReefJunkie]

It looks like it is has a air bubbles being released, but it looks like a hardened algae on the rocks. It looks like to me it is a mixture of diatoms and coraline, but the bubbles being released from the algae tells me cyano possibly. What do you all think?

These species of cyano often appear as a light slimy yet hairy/fuzzy nastiness that loosely attaches to your rock work. Air bubbles are usually trapped while escaping the "algae", just like in the picture to the left. Calothrix is a type of blue green algae that looks very similar to Dinos. We have them next to each other in the guide to help you distinguish the difference between the two.
