Seachem PhosBond 500ml
Combines ferric oxide with alumina oxide into a singular material. PhosBondTM is a revolutionary new product that combines the phosphate removing capabilities of both aluminum oxide and granular ferric oxide (GFO) into a singular material forming a synergistic effect. It rapidly removes phosphates and silicates from saltwater and freshwater, combining the best of both types of phosphate removers. Its high porosity and surface area give it a large binding capacity, while its physical strength and integrity assures that it will not break down from mechanical stress.
