How will I know that it's done cycling.. besides the Amonia/Nitrite/Nitrate being at Zero? 
 
I'm getting strands of hair algea now.. yuck. And my white sand is now a gross brownish color... how and when will that go away? 
 
I have some of that Nutrafin "CYCLE" solution.. should I add any of that now, or wait, or not at all? Has anyone ever used this in a SW aquarium?
