Overview: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.
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.
Regneration: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 (180 micron or less) filter bag such as
Seachem’s The Bag. For best results, Purigen should be placed so as to
maximize the flow of water through it. It may be used in a canister
filter, media chamber, box filter, or any high flow area of a trickle
filter. Each 250 mL treats up to 1,000 L (250 US 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-metallic container
in a well ventilated area and away from children. Use regular 8.25%
hypochlorite household bleach (non-scented, no dyes, do not use a
splash-less bleach). Rinse well, then soak for 8 hours with a solution
containing 4 tablespoons of Prime, or equivalent dechlorinator per cup
of water. Rinse well. For freshwater use, soak for 4 hours with a
solution containing 2 tablespoons of buffer per cup of water (Discus
Buffer, Neutral Regulator). 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 bleach/chlorine is detectable. In case of
doubt, soak beads in small quantity of water and test for residual
chlorine with a chlorine test kit.
