Purigen is a premium synthetic adsorbent that is unlike any other filtration product. It is not a mixture of ion exchangers or adsorbents, but a unique macro-porous synthetic polymer that removes soluble and insoluble impurities from water at a rate and capacity that exceeds all others by over 500%. Purigen controls ammonia, nitrites, and nitrates by removing nitrogenous organic waste that would otherwise release these harmful compounds. Purigen's impact on trace elements is minimal. It significantly raises redox. It polishes water to unparalleled clarity. Purigen darkens progressively as it exhausts, and is easily renewed by treating it with bleach. Purigen is designed for both marine and freshwater use.

Product Features:

• 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.
• 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, and even plants produce nitrogenous waste. Purigen removes that waste faster and more completely than anything else on the market.
• Purigen can also be regenerated. As it adsorbs waste products, Purigen will change color from a pale blonde to a dark brown, almost black. Once it is exhausted, it can be regenerated with a solution of bleach and water.
• Purigen possesses enhanced capacity owing to its vast surface area. All other resins on the market are purely spherical extruded beads. These beads remain smooth even under a microscope. Purigen® is both spherical and macro reticular.
