Seachem Purigen Organic Filtration Resin 100ml (6 Pack) - Aquarium Filter Media for Freshwater & Saltwater

Seachem Purigen is not a mixture of ion exchangers or adsorbents, but rather a unique macro-porous synthetic polymer that removes soluble and insoluble impurities from water at an excelled rate and capacity. Seachem, a company rooted in sound science, has been in the industry for over three decades, with an experienced team of chemists and biologists supporting its products. Seachem remains one of the few surviving independent and privately owned pet care companies, owned and operated by hobbyists who maintain aquariums at home and in the office.

Seachem's philosophy is that the knowledgeable hobbyist makes the best customer, which is reflected in its solid and reliable customer education and support, as well as products proven in science and performance. While the company has grown rapidly into a national and international firm, it retains the culture of a small company and is readily available to its customers.

Seachem Purigen, an organic filtration resin, works hard to remove nitrogenous compounds and waste produced by fish, corals, and even plants, making the water crystal clear. Its spherical and macroreticular design, with microscopic pores, increases its usable surface area to many times that of a purely spherical resin, enhancing its capacity.

When Seachem's Purigen is exhausted, it can be regenerated with a solution of bleach and water, which literally "burns off" the organics that have been removed from the tank. However, some slime coat products may permanently foul Purigen and render regeneration difficult. Users are advised not to reuse Purigen if the odor of bleach/chlorine is detectable, and to soak the beads in a small quantity of water and test for residual chlorine with a chlorine test kit in case of doubt.
