I added a bag of zeolite to my new 16 gal biocube to help with a startup ammonia problem which has subsided. Of course, i don't know if the zeolite actually helped or the nitrogen cycle just took hold... Or whether it even works in salt water.
The question is, can i just leave the granules in the system as additional biological media?
