FAQ: How do I use Seachem PhosBond™? How long does it work and when is it exhausted?

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.
