The Neo Bag Minus serves as a water treatment solution that effectively absorbs harmful nitrites, nitrates, and phosphates in your aquarium. These substances can be detrimental to aquatic life and tend to build up in the water, requiring frequent water changes. This product chemically binds these toxins, resulting in a longer-lasting solution as it can be regenerated for continued use. With the added benefit of being able to adsorb other negative ions, the Neo Bag Minus provides an efficient dual approach by utilizing energy spheres that release stable organic carbon and trace elements. For optimal results, use one bag per 60 liters of water, adding an additional bag for a quicker effect if needed. To maintain effectiveness, place the Neo Bag in a filter with strong water flow. Before use, rinse the bag approximately 20 times in clean water to release natural sediments.
