Does Seachem Purigen work?

In this video we look at Seachem Purigen. We get asked often if this product is any good, and truth be told, it is amazing. But instead of telling people that, we thought we would show you.
To start with we hit this 150L aquarium with some Sera Aquatan, and we hit it really hard. The water was nearly black when we put the Purigen in. Over the course of a week, Purigen did it's magic until we had a sparkling clear aquarium again.
