Seachem Purigen – 100ml Bagged (Ready-to-Use Organic Filtration Resin)

Seachem Purigen is a revolutionary synthetic filtration resin that removes organic waste more efficiently than any other product on the market. This 100ml version comes pre-packed in a fine mesh bag, making it easy to drop directly into your filter—no additional bags or containers needed.

Purigen targets nitrogenous organic waste such as fish excretions, uneaten food, and decaying matter before they break down into harmful ammonia, nitrite, and nitrate. It polishes water to unmatched clarity and is safe for all types of aquariums. The resin changes color as it becomes exhausted and can be regenerated multiple times using a bleach solution.

– pre-bagged for convenience and ease of use
– Removes soluble and insoluble organic waste
– Controls ammonia, nitrite, and nitrate levels
– Enhances redox and water clarity

Directions for Use:

Rinse before use. Place the bag in a high-flow area of your filter. Each 100 ml treats up to 400 L (100 US gallons) for up to six months. When the resin turns dark brown or black, regenerate using a 1:1 bleach:water solution for 24 hours. Follow with a dechlorinator soak (e.g., Seachem Prime®) and rinse thoroughly before reuse.

Regeneration Tips:

– Use only non-scented, dye-free bleach
– Avoid slime coat products that may foul the resin
– Do not reuse if bleach odor remains after regeneration
