Is this Coralline Algae?

[AshtonSaltwater]

Week 6. Tank is fully cycled. What are those orange/ pink spots?

I doubt it coralline but I could be wrong my tank has been up and running for 5 months and I am just starting to see little specks on the glass. Also did you seed you tank with any algea? From a snail/frag or live rock?

Agreed does not look like coralline, tank is too young and that looks like dry rock.
At 6 weeks I would expect to see diatoms and cyano or a mix of both.

Id say diatoms by the way they are growing... would have to see closer to be sure. Could be coralline in a young tank if there are frags in the system or any old rock

+1 for diatoms.

They'll go great guns for a little while, then fade away as other algaes get cranked up.
