Seachem Purigen 100ml Bag

Purigen® - Premium Synthetic Adsorbent

Purigen® is a premium synthetic adsorbent, 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%.

Key Benefits:

• Controls ammonia, nitrites, and nitrates by removing nitrogenous organic waste that would otherwise release harmful compounds.
• Minimal impact on trace elements.
• Significantly raises redox.
• Polishes water to unparalleled clarity.
• Color changes as it exhausts, making it easy to monitor usage.
• Easily regenerated by treating with bleach.
• Designed for both marine and freshwater use.

Superior Organic Filtration

Purigen is the highest capacity organic filtration resin on the market. No other product can compare to its ability to clear haziness and polish water to unparalleled clarity. Unlike other products, which are simple ion-exchange resins, Purigen is specifically designed to be an organic scavenging resin.

• Extreme affinity for nitrogenous organics: Purigen generally ignores simple elemental compounds and targets nitrogenous organics, which are primarily produced by waste from fish, corals, and plants.
• Unmatched efficiency: Purigen removes waste faster and more completely than any other product available.

Regeneration Process

Purigen can be regenerated, making it a long-lasting solution for your filtration needs. As it adsorbs waste products, Purigen will change color from a pale blonde to a dark brown, almost black. Once exhausted, it can be regenerated using the following process:

1. Soak in a 1:1 bleach:water solution for 24 hours in a non-metallic container in a well-ventilated area, away from children. Use regular 8.25% hypochlorite household bleach (non-scented, no dyes, do not use splash-less bleach).
2. Rinse thoroughly, then soak for 8 hours in a solution containing 4 tablespoons of Prime (or equivalent dechlorinator) per cup of water.
3. Rinse well again.
4. For freshwater use, soak for 4 hours in a solution containing 2 tablespoons of buffer per cup of water (Discus Buffer or Neutral Regulator).
5. Ensure no bleach/chlorine odor remains. If unsure, soak beads in a small quantity of water and test for residual chlorine using a chlorine test kit.

Caution: Some slime coat products may permanently foul Purigen and make regeneration difficult. Do not reuse if the odor of bleach or chlorine is detectable.

Usage Instructions

• Rinse before use.
• Use in a fine mesh (180 micron or less) filter bag, such as Seachem’s The Bag.
• Place Purigen to maximize water flow through it. It can be used in:
  • Canister filters
  • Media chambers
  • Box filters
  • High-flow areas of trickle filters
• 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.

Enhanced Capacity

Purigen’s enhanced capacity is due to its vast surface area:

• Unlike other resins, which are purely spherical extruded beads, Purigen® is both spherical and macroreticular.
• Its microscopic pores increase usable surface area to many times that of purely spherical resins, making it the most efficient organic removal product available.

With Purigen®, enjoy crystal-clear water and optimal filtration performance for both marine and freshwater aquariums.
