zeolite | Pigeon-Talk

Zeolite works like charcoal or carbon. It is used in aquarium filtration to remove ammonia. The problem is that once it is saturated, it releases ammonia back into the water. Further, I believe that it does something in addition to this, once saturated. I tried it for a while when I was breeding alot of fish.
