Seachem: purigen


Not sure if this has been talked about before but been looking at buying it, wandered if anyone has used it, seems good to me

http://www.seachem.com/Products/prod...s/Purigen.html

Apparently can be cleaned and re-used upto 8 times so seems good value for money.


Purigen
Product Description
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 with bleach. Purigen® is designed for both marine and freshwater use.

Sizes: 100 mL 250 mL, 500 mL, 1 L, 2 L, 4 L, 20 L

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. Use in a fine mesh filter bag. 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-metalic container in a well ventilated area and away from children. Rinse well, then soak for 8 hours with a solution containing 2 tablespoons of ChlorGuard™, Prime®, or equivalent dechlorinator per cup of water. Rinse well. 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 chlorine is detectable. In case of doubt, soak beads in small quantity of water and test for residual chlorine with a chlorine test kit.

Been using Purigen for years, love the stuff, and I've kept recharging and re-using mine for 4+ years.

Purigen does everything the manufacturer says it will do.
It's an outstanding purifier, and clarifier/polisher. I've used it for years, mainly 24/7, and I wouldn't be without it. I find I can re-generate it up to a dozen times or more, without it losing much of it's effectiveness.
Try it - you'll love it.

i use it in my new 8 gallon tank. When i re-plant my 36 gallon i plan on using it in that tank as well. water clarity is great with it, and it has turned brown a few times, i've just pulled it and washed it with very hot water and rinsed it till the water ran clean and stuck it back in.

i haven't even tried a bleach bath yet!

Sometimes people are just exited about finding a product they haven't seen before. The people that respond to repeat posts don't seem to mind, so I don't see the problem. You can always choose to ignore a thread if you don't want to respond.
