It does very similar things to activated carbon but in a different way, link below.What is purigen I don't know anything about it.

You can replace it and keep it running if you want to try and keep the tank a little clearer of tannins or go down the Purigen route.Thanks, think I will just use it for a month then.
People will argue for both sides of the fence with Purigen vs Activated Carbon but I don't think either one is better than the other.
Personally I use Activated Carbon; why? I'm not sure I just find it easy!
