What is this hairy algae all over the place?

It's been slowly growing on all sides of my tank and a little bit on my sand bed and its kind of a brownish green color. What is this and what is the best way to remove it? Should I buy a scraper and scrape it all off and let the filter pick it up? Or should I just wait till payday and order my cleanup crew from this site? It just recently appeared as I gave my tank 2 weeks to cycle and then added a little bit of live sand as well as my first clarkii clown.
