Seachem PURIGEN 100ml 200ml 300ml 400ml in a 180 micron filter bag

Description

100ml 200ml 300ml 400ml Seachem purigen comes loose in a grip seal mesh bag (Bucket not included!)  With a reusable cable tie for added protection against spillage in a 180 micron filter bag. There are two bag sizes medium (3″ x 8″) or large (4″ x 12″). The bags are great if you want to cover a larger surface area of your filter tray. Both are ideal for internal filters, canister filters or sump tanks. These filter bags are quality bags made from 180 micron nylon filter mesh so have optimal flow through for Purigen. They are stitched with very strong nylon threads so they easily stand up to the bleaching process if you regenerate your 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 others by over 500%. Purigen controls ammonia, nitrites and nitrates by removing nitrogenous organic waste that would otherwise release these harmful compounds.
For freshwater & saltwater aquariums
Purigen controls ammonia, nitrites and nitrates
Purigen’s impact on trace elements is minimal
Polishes water
Purigen darkens progressively as it exhausts, and is easily renewed by treating with bleach
Why It’s Different
Selectivity
: 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.
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
: 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. 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.
Directions
Rinse before use. Each 1 L treats up to 4,000 L (1,000 gallons*) for up to six months. Exhaustion is indicated by a pronounced discoloration of the beads to dark brown or black.
Regeneration
: 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 tablespoon of buffer per cup of water (Discus Buffer®, Neutral Regulator®). Original color and full activity should now be restored and Purigen® is ready for reuse. Caution: some slime coat products may permanently foul Purigen® and render regeneration difficult. Do not reuse if odor of bleach/chlorine is detectable. In case of doubt, soak beads in small quantity of water and test for residual chlorine with a chlorine test kit.
