Seachem Purigen

Seachem 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 other competing products by over 500%. Seachem 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. Seachem Purigen darkens progressively as it exhausts. It also renews easily by treating with bleach. You can use it in both marine and freshwater aquariums. Purigen is the highest-capacity organic filtration resin on the market. No other product 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 an organic scavenging resin. When ion-exchange resins fill 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.

Capacity

Purigen’s 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 macroreticular. It has microscopic pores that increase its usable surface area to many times that of a purely spherical resin.

Regeneration

You can also regenerate Seachem Purigen. As it adsorbs waste products, Purigen will change colour 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. The bleach will literally “burn off” the organics that have been removed from the tank.

Watch out for products that claim to be regenerable with a brine solution. That is the regeneration procedure for ion-exchange purposes. A brine solution will not remove organics. While such resins have a limited capacity for organic adsorption, a brine regeneration process only replaces removed ionic compounds. It does not destroy large organic molecules that were removed, which is the primary function of organic adsorption resins.

Rinse before use. Use in a fine mesh (180 microns or less) filter bag such as Seachem’s The Bag. For best results, you should place purigen so as to maximize the flow of water through it. You can use it in a canister filter, media chamber, box filter, or any high flow area of a trickle filter. Each 250 mL treats up to 1,000 L (250 US gallons) for up to six months. Exhaustion is indicated by a pronounced discolouration of the beads to dark brown or black.

Regeneration Directions

Soak in a 1:1 bleach: water solution for 24 hours in a non-metallic container in a well-ventilated area and away from children. Use regular 8.25% hypochlorite household bleach (non-scented, no dyes, do not use a splash-less bleach).

Rinse well, then soak for 8 hours with a solution containing 4 tablespoons of Prime, or equivalent dechlorinator per cup of water. Rinse well. For freshwater use, soak for 4 hours with a solution containing 2 tablespoons of buffer per cup of water (Discus Buffer, Neutral Regulator). Original colour and full activity will then be back and Seachem Purigen is ready for reuse. Caution: some slime coat products may permanently foul Purigen and render regeneration difficult. Do not reuse if the odour of bleach/chlorine is detectable. In case of doubt, soak beads in a small quantity of water and test for residual chlorine with a chlorine test kit.

McMerwe’s Comment: Seachem Purigen removes soluble and insoluble impurities from water at a rate and capacity that exceeds all other competing products by over 500%. [Rating 5/5]

First time using this product – really enjoy how easy it is to clean and how well it works in removing organic waste. Pricey, but worth it.

First time using this and I am impressed. Had it in my filter for a few hours and it has removed tannins in the water, which I wanted to remove. Only problem is its on the expensive side.
