brown algae?

[cheets22]

I am new to the whole saltwater aquarium thing, but I did a lot of research before setting up my tank. I even set up a trial tank to see how my real tank would survive. I have had my tank set up for 2 months now, and there have been no problems until yesterday when i discovered some brown algae like material coating one of my ornaments and my reef sand and crushed shells. I have researched thigns, but have no idea what this is or how to remove it from my tank? please help..

It sounds like Diatom algae...perfectly normal for a young tank.

If it's brown it's Diatom algae...If it's more of a reddish purple it's Cyano bacteria.
IMO don't add any chemicals until you've tried the methods suggested in these replies.
