Seachem Zeolite

What is Seachem Zeolite?

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 commercially available zeolite. It also won’t deplete calcium in saltwater, and it won’t increase general hardness in freshwater, where the ionic strength is low.

How do I use Seachem Zeolite?

For best results, Zeolite should be rinsed before use and placed so as to maximize the flow of water through it but not so that it tumbles against itself in flow. It may be used in a canister filter, media chamber, box filter, or any high flow area of a trickle filter. Use of a filter bag is recommended.

Use 250ml (1 cup) of Zeolite for every 200L (50 US gallons). For smaller aquariums, the equivalent dose is 5ml (1 level teaspoon) per 4L (1 US gallon). This amount of Zeolite will remove up to 0.5 mg/L ammonia. Monitor ammonia levels, which should drop to zero within 24-48 hours.

At this point, Zeolite can be removed or replaced with activated carbon. For heavy metals removal, leave in service and replace monthly.
