Trying to figure out what this stuff is. I went in and cleaned up a bunch on one side of the tank and the next morning there were new patches. It's Greyish and looks hairy.

Cyano. It comes in many different colors. Remove as much as you can manually, adjust more flow across your sand bed and watch your nutrients.
 
I read that depending on what kind of corals I had, I could leave the lights off for up to 72 hours and that would help.
