Seachem Purigen Premium Synthetic Filter Media for Crystal Clear Aquarium Water.
Seachem Purigen is one of the most advanced and high-performance filtration products ever developed for aquarium enthusiasts. It is a premium synthetic adsorbent that works unlike any traditional carbon or ion-exchange resin. Instead of merely absorbing impurities on the surface, Purigen’s unique macro-porous polymer structure actively removes both soluble and insoluble organic wastes from your aquarium water, making it one of the most powerful and efficient filter media available.
What truly sets Seachem Purigen apart is its exceptional capacity—over 500% greater than competing products. It is not just another chemical filter; it’s a precision-engineered organic scavenger that eliminates nitrogenous compounds before they can break down into harmful ammonia, nitrite, or nitrate. This results in healthier fish, clearer water, and a more stable environment for both freshwater and marine aquariums.
While most filter media remove trace elements and affect water chemistry, Purigen does so minimally. It significantly raises redox potential, ensuring your water remains crystal clear and oxygen-rich. Over time, you’ll notice your aquarium water achieving an unmatched brilliance—what aquarists often call the “diamond clarity effect.”
Removes organic waste at molecular level: Traps nitrogenous compounds from fish waste, uneaten food, and decaying plants.
Controls ammonia, nitrite & nitrate naturally: Prevents buildup of harmful toxins before they form.
Enhances water clarity dramatically: Leaves your aquarium water sparkling clear for months.
Regenerable and long-lasting: Easily renewed using a bleach-water solution, reducing long-term maintenance costs.
Safe for plants, fish, and corals: Designed for both freshwater and marine aquariums with minimal impact on trace minerals.
500% more efficient: Performs far better than carbon, zeolite, or other adsorption media.
Purigen’s macro-reticular structure features microscopic pores that exponentially increase its usable surface area. This allows it to trap organic molecules deep within the polymer network. When the resin turns from pale blonde to dark brown, it indicates saturation. Simply regenerate it using Seachem’s recommended bleach method to restore its full performance.
For aquarists who value clarity, performance, and longevity, Seachem Purigen is the go-to choice. It goes beyond mechanical or biological filtration to remove what you can’t even see—dissolved organics that cloud water and degrade water quality. With consistent use, it helps maintain a pristine ecosystem, ensuring your fish thrive in the purest environment possible.
Rinse before use.
Place in a fine mesh filter bag in a high-flow area of the filter.
When exhausted, regenerate with a 1:1 bleach-water solution.
Use with caution; always neutralize chlorine before reuse.
