Seachem Zeolite™ is a naturally occurring, highly-porous mineral that binds ammonia and heavy metals through an ion exchange mechanism. It has the highest ammonia binding capacity of any available zeolite; ten times higher than some products and twice the capacity of the closest competitor. It won’t deplete calcium in saltwater, and it won’t increase general hardness in freshwater, where the ionic strength is low.
