- 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.
A Dedicated Purigen Filter
Customer Reviews
I tried water changes, other additives, even adding another filter to my 55 gallon tank and still had a nitrate issue. This did the trick and my water is crystal clear
Cleared tannins in 2 days
I use it to clear out the tannins. Does a great job at that!
Great product but I do wish it came with 2 bags (half as big).
