About this product

Ensure exceptional water clarity and superior filtration with Seachem Purigen, the premium bagged organic filtration resin designed for both freshwater and marine aquariums. In the convenient 250 mL bagged format, this resin excels at removing soluble and insoluble organic waste—thereby helping reduce ammonia, nitrite, and nitrate levels. Key Features: Unique macro-porous synthetic polymer media with significantly higher surface area than typical ion-exchange resins. Controls ammonia, nitrite and nitrate by removing organics before they break down. Bagged form makes it easy to insert into filter compartments, media reactors, or suspension chambers. Suitable for freshwater, planted, marine or reef aquariums. Colour-change Usage Instructions: Rinse the 250 mL bag in aquarium water (not tap-chlorinated) before placing into your filter system.

For best results: 250 mL treats up to 1,000 L (≈250 US gallons) for
