What is the green algea on my live rock

[jasonb87]

Only some of the rock it's on is new. The other rocks are over a year and half old in this tank. Bought the tank from a friend and got the parameters in check. Put T5 lights on temporary and my new LEDs will get put on this weekend

This is not coralline algae. It is a natural process new rock goes through. Coralline grows from the center out. As you can see from the pics, this is not the case. Yes it does come in many colors but this is not coralline. The rock will be covered with coralline in time if par. are kept good.

Coralline can grow from many small spots at once and spread in the way the pics are showing. Is the algae have a texture or is it just hard like rock?

It will go away. Patience

There's also cyano on that rock.

+1. You need more flow! I still think it's coralline... unless it's fuzzy. Is it going away yet or spreading more?
