They say "Purigen removes proteins, nitrates, nitrites, ammonia and a broad spectrum of organics, yet its impact on trace elements is minimal. It significantly raises redox.

While I tend to think those claims are pretty grand, I agree that Seachem is a reputable company that generally doesn't go overboard in its claims.
As far as knowing if it does all this, all I can go by is my experience using it. My test results, even with water changes every 2 weeks are alwasy excellent. My water has never been clearer - and my fish are very healthy and active. Is that scientific proof - no, but its good enough for me.
I'm concerned about the things we can't easily measure, but that may have an affect on our fish over the long haul. Where do pheromones fit into this, I wonder...
Well, Purigen actually changes colors when it is working. It is white out of the jar - and darkens progessively as it exhausts. Once it is dark brown, it is no longer effective and needs replaced or regenerated. So it is easy to tell if it is no longer working.
Hope this helps. As I noted, I know folks will be skeptical - shoot, I am skeptical of many things, but before using Purigen, I searched the net and found several satisfied users - and my experience to date has proven positive. Really though the only way you will probably ever be sure is to try it and test it yourself.
