- Absorbs Ammonia, Nitrite & Nitrate
- Removes Tannins From Water
- Improves Water Clarity
Purigen is a filter media designed to absorb organic waste such as ammonia, nitrites and nitrates at an incredible rate. When in use, it makes for a crystal clear water column. It is extremely helpful if being used to remove tannins as well. It is not known to remove aquatic fertilizers. Over time, Purigen will darken from white to brown so you can visually tell when it has been exhausted. Many hobbyists won't run a tank without it.

This is my go to for crystal clear water in all my tanks - it’s one of the products I can say for certain makes a noticeable difference in 24 hours.
