Seachem Purigen Organic Filtration Media 500 ml

Keep your aquarium water crystal clear and your aquatic life thriving with advanced filtration technology. Enjoy a cleaner, healthier, and more balanced environment for your fish and plants. Seachem Laboratories Purigen Organic Resin Filter 500 ml is a premium synthetic adsorbent designed to provide superior removal of soluble and insoluble impurities. Seachem Resin Filters for Aquariums outperform competing products, effectively reducing ammonia, nitrite, and nitrate levels. As one of the best fish tank filters, it helps polish water to unmatched clarity while preserving essential trace elements. This unique resin regenerates easily, offering long-term value and consistent performance for both freshwater and marine aquariums.

Purigen is a macro-porous synthetic polymer with both spherical and macroreticular structure, providing an exceptionally high surface area for absorption of nitrogenous organic waste. It is chemically inert, safe for freshwater and marine aquariums, and retains essential trace elements while removing impurities.

• Handle bleach regeneration carefully; never return untreated Purigen to the aquarium.
  
• Do not use with chloramine-removing products during regeneration, as this may leave toxic residues.
  
• Keep out of reach of children and pets.
• For aquarium use only; not for human or animal consumption.

• Use 250 mL Purigen per 1,000 L (250 US gallons) of water.
  
• Place in a filter bag inside a canister, box, or other aquarium filter.
  
• Purigen darkens as it exhausts; regenerate when it turns dark brown/black.
  
• Regenerate by soaking in a 1:1 bleach: water solution for 24 hours, rinse thoroughly, then soak in a dechlorinator solution before reuse.
• Avoid using brine solution for regeneration, as it does not remove organic waste.
