I have a 20g reef tank I setup 4 months ago. about a month ago this brown algae started showing up. It got thick quickly and isn't going away. (see attachment pic)

2. Can\Should\How I clean\scrub it off?
3. How do I get rid of it?

It's only growing on the rocks where the light shines and not on the sand.
