Seachem Purigen Ultimate Filtration Powder
Seachem Purigen Ultimate Filtration Powder ('116016308)

Seachem Purigen Ultimate Filtration is a premium synthetic adsorbent that, unlike any other filtration product, 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 others by over 500%.

  • Removes soluble and insoluble impurities from water
  • Controls ammonia, nitrites, nitrates
  • Polishes water to unparalleled clarity

Purigen controls ammonia, nitrites and nitrates by removing nitrogenous organic waste that would otherwise release these harmful compounds. Purigens 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.

Why Its Different:

  • 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: Purigens 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.
  • Regeneration: 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 filter bag. Each 1 L treats up to 4,000 L (1,000 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-metalic container in a well ventilated area and away from children. Rinse well, then soak for 8 hours with a solution containing 2 tablespoons of ChlorGuard, Prime, or equivalent dechlorinator per cup of water. Rinse well. 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 chlorine is detectable. In case of doubt, soak beads in small quantity of water and test for residual chlorine with a chlorine test kit.

Seachem Safe Powder
Seachem Safe Powder ('116038706)

Seachem Safe Powder is a concentrated dry conditioner for freshwater and saltwater aquariums. This concentrated conditioning powder removes chlorine and chloramine from tap water, detoxifies nitrite and nitrate, and converts ammonia into a safe, non-toxic form for more efficient removal by the biofilter.

  • Removes chlorine, chloramine and ammonia from water
  • Detoxifies nitrite and nitrate
  • Non-acidic, highly effective dry conditioner for fresh and saltwater

Seachem Safe Powder will not impact pH levels or overactivate skimmers. It may be used during tank cycling to alleviate ammonia/nitrite toxicity, during start-up or whenever adding or replacing water.

Note: Safe is the dry version of Seachem Prime and shares all of its advantages; however, Safe is even more concentrated than Prime.

Directions for Use:
Note: These directions supersede all other prior packaging.

Directions for 10 g and 50 g:
Use 100 mg Safe (scoop) per each 100 L (25 gallons) as needed to reduce chlorine and chloramine or per 25 L (6 gallons) for ammonia.

Directions for all other sizes:
Use 1.25 g (1/4 tsp.) for every 1,250 L (300 gallons) as needed to reduce chlorine and chloramine or use 1.25 g (1/4 tsp.) for every 300 L (75 gallons) for ammonia.

May be added to aquarium directly, but better if added to new water first. If adding directly to aquarium, base dose on aquarium volume. For exceptionally high chloramine concentrations, a double dose may be used safely. To detoxify nitrite and nitrate in an emergency, up to 4 times normal dose may be used. If temperature is > 30 °C (86 °F) and chlorine or ammonia levels are low, use a half dose.
