Algae Identification

[brichard925]

What type of algae is forming? Only on the dry rock. Looks to me like GHA but I am a beginner. Have gone through diatoms and that cleared up on its own after a few days and wondering what this is and if I need to just wait it out. I have a small cuc in the 25 gallon tank.
Thanks.

Looks like the beginning of gha and will probably get worse. Normal for starting with dry rock.

When it starts taking off check out reefcleaners.org for a cleaner package.
