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.
For best results, this should be rinsed before use and placed so as to maximize the flow of water through it, but not so that it tumbles against itself in flow. It may be used in a canister filter, media chamber, box filter, or any high flow area of a trickle filter. Use of a filter bag is recommended. Use 60 milli litres (1/4 cup) for every 200 liters saltwater or 400 liters freshwater. Leave product in place for days, then test phosphate or silicate concentrations with either Multi test Phosohate or Multitest Silicate. If the concentration of the component you are trying to decrease has not dropped to around 0.02 milli grams/liter, then replace the PhosBond, otherwise leave in place until levels begin to climb again. As long as concentrations remains under control, the product is not exhausted.
Over treating is not recommended. This is not an exchange resin and does not release anything into the water. It does not leach phosphate or silicate back into the water and may be removed, dried, and returned to service until exhausted. Continuous use of small qualities is better than intermittent use of larger quantities.
