The 250 ml container of Seachem Purigen is a tool that every hobbyist, both beginner and advanced, should have in their aquatic tool kit. It is a scientifically formulated premium synthetic adsorbent that is not a mixture of ion exchangers or adsorbents, but a unique macro-porous synthetic polymer that removes soluble and insoluble impurities from both freshwater and saltwater at a rate and capacity that exceeds all others competitive products by over 500%. The formula helps to control ammonia, nitrites and nitrates by removing nitrogenous organic waste that would build up and release harmful chemicals into your aquarium water column, negatively impacting all aquatic life within the aquarium. Though, Purigen's impact on beneficial trace elements in minimal, it significantly raises redox and polishes water with unparalleled clarity.
API® WATER SOFTENER PILLOW is ideal for soft water aquariums. These ready-to-use pouches contain resins to remove calcium, magnesium and soluble heavy metal ions, including copper and iron.
To add to the already incredibly functionality of this product, Purigen can actually be regenerated to retain efficiency and effectiveness in the long term. As it adsorbs waste products, the beads will change color from a pale blonde to a dark brown, nearly black coloration. 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. Brine solutions will not remove necessary harmful organics. While such resins have a limited capacity for organic adsorption, a brine regeneration process only replaces removed ionic compounds and it does not destroy large organic molecules that were removed, which is the primary function of organic adsorption resins in the first place.
