Seachem Purigen

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%. 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.

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.

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.

Perfect "To Go" Untuck Shirt for all summer events!
Size: XX-Large, Color: White-all White
LOVE LOVE LOVE this shirt! Great quality. The material is soft and just thick enough to not be see-through but cool for our Southern summers or tropical locations. The only thing I would say is depending on your arm to shoulder size, you may want to go up a size. I originally bought an xl for my husband, but it was a little snug at arm hole area, so we exchanged it for a xxl (it is designed so you do not have to tuck it in so the xxl fit and looks great.) I reordered in the blue also. Excellent for weddings, dinner, outings etc.. definitely recommend!

Nice and comfy, light duty and feel great.
Size: X-Large, Color: Light Green
What they may lack in "durability" i.e. very light and thin = not going to last all that long, they make up for in fit [yes even for wide shoulders], comfort and style. If you want them to last, suggest a gentle cycle and just take ot easy on them. They are light, thin, and airy. Nice summer shirt.

Nice shirt
Size: Medium, Color: Light Green
The shirt is true to size. I'm 5'10" and 160 lbs. and the medium fits well. It is light and airy, and after light pressing holds its shape well. The little cuff on the sleeve is a nice touch. Be aware that the buttons are hidden (if that's the look you're going for). I can't speak to durability as I have only worn it once. I have several Coofandy shirts and they are all nice garments.

Great for the price
Size: Medium, Color: Grey
Nice and light material. Looks good. Suitable for hot temperatures and casual attire. The only thing I've noticed so far that isn't so great, is that the buttons are rather cheap and the middle part broke out on a few of them. Expect to resow some buttons. Otherwise great
