Seachem PhosBond

PhosBond is an innovative product that fuses the phosphate - removing powers of aluminum oxide and granular ferric oxide into one material, creating a powerful synergistic effect. It quickly eliminates phosphates and silicates from both saltwater and freshwater aquariums, bringing together the top features of two types of phosphate removers. With high porosity and a large surface area, it has an excellent binding capacity. Its strong physical structure ensures it won't break down under mechanical stress. This product comes in convenient sizes: 100 ml, 250 ml, 500 ml, and 4 Litres.

To use PhosBond, simply place it in your aquarium's filter. It'll start removing phosphates and silicates right away. When it comes to the amount, follow the instructions according to your aquarium's size. As a note, don't let it get too dirty. If you notice a drop in its performance, it might be time to replace it. You can keep it in good shape by making sure it's not crushed or damaged in the filter. This will help it last longer and keep your aquarium water clean.
