What type of algea is this?

[SomeHappyFish]

Its neon green...

Looks like common green algae that occurs in new tanks/on new dry rock.

Edit: although if it's hard (doesn't brush off), it might be the beginning of coraline algae.

I attempted to brush it, but it's tough and hasn't come off. My conch came with lots of coraline so my guess is also coraline algea!

Just looks like plain green slime algae that all new tanks get starting with dead rocks.

Looks like the ground work for coralline algae to me.

Agree on slime algae and often due to intense white lightingg or tank at ior near a window. Its more unsightly than it is an issue and can easuily be brushed off with a firm toothbrush.
Adding snail will help with control such as : Astrea, cerith, nerite and turbo grazer. Even a few Carribean Blue leg hermits which are tiny

Remove the rock and place in a container of tank water and brush with Hydrogen peroxide added. If its really stubborn, fiberglass, not steel wool will for sure loosen it

Looks like green algae as others have said if it bothers you add some snails.

You should just leave it be. It is part of a new tank development phase. Cleaner crew is the best natural option. You will be experiencing a variety of ugly phases over the course of your first year and perhaps beyond.

@SomeHappyFish , please don't do this. You'll kill the coralline algae!

It's a start

 

[Not_Erick]

You can just leave it, it should resolve on its own

 

[alindell]

Yah that algea doesn't really bother anything. Just unsightly. Usually disappears and Coraline takes over

Looks like it's transforming into coraline, so I will leave it !

So many wrong answers, as others said... a precursor to coralline, in short a good sign.
