Seachem Purigen 100ml Bagged
Seachem Purigen® is a premium synthetic adsorbent resin designed to deliver crystal-clear aquarium water by removing soluble and insoluble impurities with unmatched efficiency. Unlike traditional ion-exchange resins, Purigen® is a unique macro-porous polymer with an extreme affinity for nitrogenous organic waste—the primary source of ammonia, nitrite, and nitrate in aquariums.
With over 500% greater capacity than competing products, Purigen® not only controls harmful compounds but also significantly raises redox levels and polishes water to unparalleled clarity. Safe for both freshwater and marine systems, it leaves trace elements intact while powerfully targeting waste. As it becomes exhausted, Purigen® changes color from pale blonde to deep brown, clearly showing when it’s time for regeneration.
Best of all, Purigen® is rechargeable—simply restore it with a bleach solution, making it a cost-effective and sustainable choice for serious aquarists.
