Seachem Purigen Ultimate Filtration For Marine & Freshwater Aquariums is a premium, synthetic adsorbent that is unlike any other filtration product — rather than a mixture of ion exchangers or adsorbents, Purigen is a unique macro-porous polymer that removes soluble and insoluble impurities from water. It controls ammonia, nitrites and nitrates by removing nitrogenous organic waste that would otherwise release these harmful compounds. It significantly raises redox and polishes water to unparalleled clarity, with minimal impact on trace elements. Some slime coat products may permanently foul Purigen and render regeneration difficult. Do not reuse if odor of bleach/chlorine is detectable. In case of doubt, soak beads in small quantity of water and test for residual chlorine with a chlorine test kit.
Features:
- High organic removal capacity clears haziness and polishes water to unparalleled clarity and minimally impacts trace elements.
- Large surface area for enhanced capacity compared to traditional spherical extruded beads.
- Purigen had microscopic pores that increase the usable surface area.
- Removes soluble and insoluble impurities from water by means of a macro-porous synthetic polymer.
- Helps control ammonia, nitrite and nitrate by removing nitrogenous organic waste before it can release harmful compounds.
- Purigen can be regenerated once it's changed from blonde to dark brown.
- Refresh it with a solution of bleach and water to remove organics that have been trapped.
