Purigen Seachem 500ml Controls Ammonia Nitrites Nitrates Aquarium Fish Tank

Seachem Purigen Resin. Purigen controls ammonia, nitrites and nitrates by removing nitrogenous organic waste that would otherwise release these harmful compounds.

• Purigen is the highest capacity organic filtration resin on the market. No other products can compare to its ability to clear haziness and polish water to unparalleled clarity.
• Unlike other products on the market which are simple ion-exchange resins, Purigen is specifically designed to be an organic scavenging resin.
• When ion-exchange resins are filled to capacity by metals and other contaminants, Purigen has barely begun to reach its potential.
• 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, even plants produce nitrogenous waste.
• Purigen removes that waste faster and more completely than anything else on the market.
