Its just diatoms and it will go away in a few weeks. Yu can syphonit off or stir it up and let it dissapate, and there are some critters that will eat it, or just let it go and it will go away. I take it yur tank is a new setup, and its perfectly normal to acquire diatoms at this stage of the game.
