Zeolite is used in most of our TopMix potting medias to aid in the CEC (Cation Exchange Capacity).

The active ingredient in zeolite is clinoptilolite, a mineral with remarkable properties. Let’s delve into these features:

High Surface Area: Clinoptilolite possesses an exceptionally large surface area. This extensive surface provides ample room for interactions with other substances.

Three-Dimensional Cage Structure: Imagine an infinitely extending, three-dimensional cage-like structure. Clinoptilolite’s lattice forms this intricate framework, creating internal pore spaces that can trap various molecules.

Chemical Capture via Cation Exchange: Clinoptilolite exhibits a fascinating ability called cation exchange. Here’s how it works:

When pollutants (such as ammonia) come into contact with clinoptilolite, they are attracted to its surface.The mineral’s cage-like structure allows it to selectively capture cations (positively charged ions) from the surrounding environment.

In exchange for these captured cations, other cations (such as sodium or calcium) are released from the clinoptilolite lattice.

This process effectively removes pollutants from the water or air.
