What is Purigen and how does it work?

[t0mmy108]

I tried to ask this on another forum, but no one knows.

i guess not many have used it,

Purigen, is used in place of carbon by some & use to absorb pollulents in the water. It has a mult-resin composite, also reducing N's/P's. Because of this function, it should not be used with the ZEOvit method, as these nutrients are reduced evenly by ZEOvit. Bob

As bob said... it removed organics and polish's water. Once exhausted the media will brown out which you will need to replace or regenerate. What else do you want to know?

Purigen is a great product, and does work as advertised. I have used it in the past, and probably still would be, if I were not using zeovit.

my interest in the product ends where Bob indicated it should not be used with the Zeovit method. Since I'm happy with the results with zeo, I'll stick with carbon. I just plumbed a 70 gallon prop tank to my main system. The Zeovit doses that I've been using have been established for 200 gallons of water volume. Being that I started Zeo on March 17 and have changed out my rocks two weeks ago with 2 new bags, will I need to add more rocks and up my dosage? The new tank is BB with basically water and eggcrate.

I run my Ca Reactor effluent passively through a pouch of purigen. Don't know if it is doing any good or not. But I figure any P04 coming from effluent should be removed.

Marshal, that is a good idea, but I question Purigen's ability to reduce P04's as it's a resin absorber: Have you P04-tested your effluent before Purigen then again after to test the difference? Thnx. Bob

I don't "like" to use synthetic resins in marine filtration configurations ... why pay for synthetic resins when you can maintain microfauna and bacterioplankton, and implement good husbandry techniques, to do the same thing? ... unless there exists a special circumstance, such as the inability to use a skimmer in a nano tank and personal time limitations.

10. Polymers and carbon that bind organics. These are similar to skimming in that they remove organics from the system, preventing them from degrading and contributing to the organic load. Examples are Purigen by Seachem and Poly-Filters by Poly-Bio-Marine. I’ve not used any of these for this purpose, and have not heard of others significantly reducing elevated nitrate levels with them.

The Dr. Holmes-Farley article is a good read ... as is typical of his work, IMO.

Thats the problem. Some people wouldnt have a clue how to maintain the above.
