As fish feed, they naturally create ammonia that can quickly contaminate a confined aquatic habitat. Because of its high cation exchange capacity, St. Cloud Zeolite can be used to capture and bind ammonia in managed environments such as fish farming, fish aquaria and fish transportation.

The affinity of St. Cloud Zeolite for some forms of nitrogen also makes it capable of producing oxygen enriched air for water system aeration.

Zeolites and Bacterial Activity

As a substrate in biological filters, St. Cloud Zeolite provides an adaptive environment for the cultivation and sustainability of the bacterial populations required in the deconstruction of ammonia, (NH3) to ammonium (NO4).

Ammonia levels can fluctuate and threaten bacterial populations and the utilization of St. Cloud Zeolite can act to modify the effects of such fluctuations and contribute to sustained beneficial bacterial activity.
