Melosu's comments and links pretty much cover it. But I just wanted to add that GAC or Purigen really won't take out nitrates or ammonia itself. They will reduce the organics that will eventually turn into nitrates and ammonia though. Maybe it's just semantics, but don't expect to put GAC in a tank full of nitrates and expect the nitrates to go away.

I totally understood that the GAC was not the magic bullet in nitrate control. I just never fully understood exactly why we use chemical media 100% I think I now have a better understanding of it for sure.
