Algae Identification

What type of algae is this? I have pink and purple coralline that appears to smoothly coat the rock. This appears to plate the rock and has white, fine-sand-size white specks. Is this coralline too? Thanks!

Coralline will grow like that too

I believe it is coralline algae. If so, the white spots are patches of dead coralline.

It looks like coralline to me as well.

Thanks. I was thinking the same thing. As I am watching the older growth, it is becoming more solidly colored, losing the white specks. Getting a little darker pink. I had taken that piece of rock approximately one month ago and scraped it with a knife, seeding the aquarium with coralline. It was almost white (bare rock) when I got thru with it. The picture that I posted was taken last week and shows all the new growth on it. After this seeding, Coralline is beginning to grow more on the tank glass and fixtures (power heads, tubing, etc...) and other rocks. But I was surprised to see it grow in plated like that with the specks in it. I was hoping I didn't make other unwanted algae grow as it is spreading very fast on that rock. Thanks for your input.
