You really need to do some reading up on your new tank before you go much further so you know what to expect. The hair algea, and some other algeas, diatoms, cyanos and a lot of other stuff your going to see are all part of the 'cycle' your tank is still going going through.

Look up "clean up crew" at some the sponsers sites and you'll find lots of recommendations on what you need. ReefCleaners.org has a form to fill out to suggest what you need and a short article about algea and cycles.

And keep posting questions here, we love answering them!
