Yellow Algea growing in my tank suddenly

[Superboy1122]

I woke up this morning and there is a bright yellow Algea growing on the back of my tank and the top of my power head and filter. What do I need to do in order to get rid of it?

Bright yellow? Never heard of it. I've heard of yellow coraline which if that's the case leave it. Coraline is good.
