Purigen® is the highest capacity organic filtration resin on the market; a tool that every hobbyist, both beginner and advanced, should have in their aquatic kit. No other products can compare to its ability to clear haziness and polish water to unparalleled clarity. Purigen® is specifically designed to be an organic scavenging resin. Purigen® generally ignores simple elemental compounds, having an extreme affinity for nitrogenous organics. The primary source of nitrogenous compounds in an aquarium is waste. Fish, corals, and even plants produce nitrogenous waste. Purigen® removes that waste faster and more completely than anything else on the market. Highest organic removal capacity Helps control ammonia, nitrite, and nitrate Advanced ability to clear haziness and polish water to look crystal clear Suitable for both freshwater and saltwater Color changes as it exhausts; can be regenerated and reused multiple times
