New algae ID :D


New member
Hey guys, my tank has been running for nearly a month and it's coming on the last phase of the cycle.
There are a couple different types of algae growing on the live rock, and I want to make sure these alga are safe for reefing. Of course I've been trying to ID it myself, but I'd rather hear it from an experienced reefer.
Neither has really grown enough in order to feel a texture, it just feels like rock.
I don't wanna invest money in fish/snails if this algae poses a threat.
Thank you in advance :D

Just cyano.. Typical in a new tank.

As you reduce nitrates & phosphates, increase flow, and increase clean up crew you should be able to get a handle on it.
