- 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.
Customer Reviews
I love this stuff. It feels like cheating, but who cares! Just make sure you mix it up when you clean your filter so you get even coverage on all the medium. It’ll last longer.
Crystal Clear. It blows me away. And I’m no way some pro at this.
This completely changed my tank to a murky cloudy mess to a crystal clear scene.
Will buy again
Cleared my tank up over night! Came home from work to a crystal clear tank.
I started using Purigen to remove Tannins from new drift wood and I continue to use to maintain clear water.
This product is excellent! Although we have purchased the large container and "bagged it" it ourselves in the past, I find it handier overall just to buy Purigen pre-packaged in this manner. The bag easily tucks into AquaClear and Marina Slim HOB filters. Purigen can turn a nano tank, full of tannins, into a clear-water tank ... virtually overnight.
Work great at removing tannins
This stuff works great. I used it on my 29 gallon tank and within two days the water was crystal clear.
Really not necessary but for that crystal clear water 🤌
