Seachem PhosBond is a revolutionary new product that combines the phosphate removing capabilities of both aluminum oxide and granular ferric oxide 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.

• 250 ml size
• Use 60 ml for every 50 gallons of saltwater or 100 US gallons freshwater. Leave product in place for 4 days, then test phosphate or silicate concentrations with either the Seachem MultiTest Phosphate Test Kit or the Seachem MultiTest Silicate Test Kit.
• It may be used in a canister filter, media chamber, box filter, or any high flow area of a trickle filter. You might want to purchase a filter bag for the PhosBond.
