FAQ: Does Stress Coat foul/ruin your Seachem Purigen® product?

If they use an amine based polymer it will not foul the resin but will render it non-regenerable. What amine based polymers will do is bond not just to Purigen® but to any organic scavenging resin as well as any ion exchange resin and when you attempt to regenerate the resin they will then bond with the chlorine to form chloramine which can be released into the aquarium. This is not just an issue with Purigen® but with all resins being sold in the pet trade. The problem only occurs when one attempts to regenerate the resin, there is no problem unless you wish to regenerate the resin you are using. Seachem® products do not contain amine based polymers and are safe to be used in conjunction with not only our resins but also with other companies resins.
