Zeolite 5kg with filter media bag

Zeolite chunks when added to a pond will take in any toxic ammonia that is present in the water in exchange for harmless sodium ions. Eventually the Zeolite will become saturated and no longer effective, so it will need to be soaked in a strong solution of saltwater to be recharged.

For improving water quality by removing ammonia.

5kg bag of Zeolite chunks complete with Filter Media bag-will treat up to 1500 gallons.
