| For chemical neutralizaton of ammonia which is very toxic to fish, the Rena Filstar XP zeolite pouch is an excellent choice. Zeolite Ammonia Remover is a natural ammonia-removing mineral for use in freshwater aquariums. It works well in both newly set-up aquariums to help prevent "new tank syndrome" and in established aquariums to prevent sudden "surges" in ammonia. Zeolite Ammonia Remover is fully rechargeable "reactivated" and works in all types of freshwater aquariums. |
