The Neo Bag Zeolite is a natural adsorbent that effectively removes ammonia and heavy metals like lead and zinc from aquarium water. Through its ion exchange mechanisms, this porous mineral can also reduce nitrate buildup, preventing the need for frequent water changes and inhibiting the growth of algae. Additionally, it aids in creating a balanced ecosystem by providing organic carbon to support the growth of beneficial bacteria, which helps break down harmful nitrogen compounds and other pollutants. With two types of energy spheres that release organic carbon and trace elements, Neo Bag Zeolite offers a comprehensive solution for maintaining clean and healthy aquarium water. To get the best results, we recommend using one bag per 60 litres of water, although a second bag can be added for a faster effect if needed. For optimal performance, place the Neo Bag in a well-flowing filter as its effectiveness may be reduced in slow-moving water. Before use, rinse the bag approximately 20 times in clean water to release natural sediments.
