Purigen High Quality Organic Aquarium Filter Resin
Purigen removes organic waste from aquarium water which if not removed would convert into harmful ammonia and nitrite and eventually nitrate. It is a synthetic adsorbent that works at a rate of 500% above other aquarium filter media to leave your aquarium with sparkly clean water.
What makes Purigen Filter Media so good?
Purigen is not an ion-exchange resin and has a far greater ability to absorb nitrogenous compounds with an un-paralleled capacity to store this waste. The huge capacity of Purigen to hold organic waste is due to its unique molecular structure. Unlike other filter media resins which are spherical in structure, Seachem Purigen is macroreticular and spherical in shape with microscopic pores that give a far greater usable surface area than other filter media.
How do I know when Purigen is fully absorbed?
Once full Purigen will turn black. As Purigen absorbs organic impurities its colour will gradually change from its original pale blonde colour becoming darker brown and eventually turning black. When this happens you can regenerate Purigen by soaking it in a solution of one part bleach to one part water for 24 hours. This process must be carried out in a non metallic container and a well ventilated room well out of reach of children. This bleaching will burn off the absorbed organic waste. Once bleached you should rinse the Purigen thoroughly and then re-soak it in water with a couple of tablespoons of Prime or other type of dechlorinator added per cup.

excellent product works a treat
This stuff is magical. I had my water slightly tinted due to bogwood. It polished the water in 24hs. Absolutely fantastic. The product I received came in a sealed mesh bag containing 100ml, that should be able to treat up 400 litres. Fits perfectly in my internal filter.
I use this a marine reef tank. Prior to using Purigen, my nitrate levels were very low and all other parameters were normal. Within a few hours of using Purigen the water appeared to be clearer, so it was removing something my existing filtration system wasn't. The colour change is noticeable and is a reasurring way to know that it is working. The ability to recharge this media is a bonus and justifies the high price tag. Note that the product doesn't come with a fine mesh bag.
