Good? Bad? Or the Ugly? - Green Algae ID

[Ommeh]

Hi everyone,

Just checking to see if this is good or bad or ugly algae.

I've read lime green algae could mean coralline so wanted some help in ID this algea which started growing this last week.

Thanks!

It does look like a the beginning of coralline algae to me.
