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, PhosBond™ 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 mL (¼ cup) for every 200 L (50 US gallons) saltwater or 400 L (100 US gallons) freshwater. Leave product in place for 4 days, then test phosphate or silicate concentrations with either MultiTest® Phosphate or MultiTest® Silicate. If the concentration of the component you are trying to decrease has not dropped to around 0.02 mg/L, then replace the PhosBond™, otherwise leave in place until levels begin to climb again. As long as concentrations remain under control, the product is not exhausted. Over treating is not recommended. PhosBond™ 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 quantities is better than intermittent use of larger quantities.
A: PhosBond™ Is best used in smaller quantities and changed frequently. In an environment with an excessively high phosphate reading, PhosBond™ will exhaust rapidly (4 – 5 days). Place the product in a high flow rate area and test your phosphate levels, changing as needed. When you see that your level is below 0.2 ppm (mg/L) leave that portion of PhosBond™ in the filter. Continue to test weekly for phosphate until you see it begin to rise again. You will then know that it is time to change the PhosBond™. If you have low levels of phosphate the PhosBond™ will absorb the silicate in your system. It’s inert and safe to leave in your filter.
A: Not at all! If it takes a phosphate absorber several months to reach its full capacity when the tank has high phosphates, it means that the media is exceptionally slow at absorbing phosphate. PhosBond™ needs to be replaced every 4 days as long as there is a phosphate problem because, given an infinite amount of available phosphate, PhosBond™ absorbs phosphate so quickly that it reaches its full capacity in 4 days. The 4 day replacement period is a function of how quickly the media works, not a function of how high a capacity the media has.
A: The main difference between these medias is capacity. PhosGuard has the lowest capacity at 0.82 mg/g of PO4 bound, but is the most economical of the four medias. PhosBond™ has a higher capacity than PhosGuard at 1.19 mg/g of PO4 bound, and combines the benefits of PhosGuard and a pure GFO (strength, high capacity, and rapid phosphate absorption) while still being very economical. PhosNet™ has the highest capacity of the Seachem phosphate absorbers at 1.41 mg/g of PO4 bound, and is a pure GFO media. Our aquavitro® phosfiltrum™ is a super-high capacity GFO (1.71 mg/g of PO4 bound) that produces very little dust. This media has a higher capacity than any other GFO on the market.
