ID this algae for me please

[ASIN28]

Hey all,
I’m gonna make this a two for one question thread so I don’t have to make two separate threads.
I noticed I’m getting some thick almost looks like turf or grass like algae on the rocks in the one photo? What is the ID and how do I get rid of it?
And
In the other photo, is this aptasia or something else? Does not look like aiptasia to me.
Thanks

Can't say for sure but looks like the start of GHA to me. Also looks like you have some green palys.....doesn't look like Aptasia.
