Zeolite helps remove any large ammonia problems. When Zeolite chunks are added to a pond they remove any harmful ammonia and      exchange this for harmless sodium ions.  However it should not be used as a substitute for a filter, but to complement an existing      system.

There are a limited number of times that Zeolite can be used, before the ion exchange is exhausted and on longer available to      uptake ammonia.  By placing the Zeolite in a strong solution of salt water for 24 hours it becomes re-charged.  Ammonia is swapped      for sodium and returns it is original state.
