If its a new tank with no inhabitants its diatoms and will go away eventully, its a cycle thing, but if you have stuff in the tank and are feeding it will take longer, but it should still balance out. If you dont see an imporvment in a couple days, i would sugest a water changed, but i dont even follow my own advice, cycleing is a slow process and will take time.
