Seachem Purigen 250 mL Premium Organic Filtration Media Crystal Clear Water Freshwater & Marine Safe
Seachem Purigen 250 mL is a premium, regenerable filtration resin designed to remove organic waste before it breaks down into ammonia, nitrite, and nitrate. Unlike activated carbon, Purigen selectively targets soluble and insoluble organic compounds, delivering exceptional water clarity and reduced nutrient buildup.
Purigen enhances light penetration, improves overall water quality, and supports healthier environments for fish, plants, corals, and invertebrates. As it becomes exhausted, the resin darkens in color, providing a clear visual indicator when regeneration is needed.
The 250 mL size is ideal for larger aquariums, canister filters, sumps, and high-bioload systems, offering outstanding long-term value thanks to its ability to be fully regenerated multiple times.
