Review on Seachem Purigen 1000ml: One-Stop Solution for Crystal Clear Aquarium Water by Kelly Thompson

Great product if only they had different bag sizes, better closing ability, better prices etc. I think they lack all of the above and once they have a competitor they need to be verified. I'm wondering if the product has to be so small that it makes a mess? If that's little enough to knock out other pocket competitors, then they've made a mistake that will hopefully cost them dearly. And they need to improve their bag and add more features.
