What are the dose rate and costs of applying Phoslock?
The dose of Phoslock varies between the water bodies. It depends on the amount of bioavailable and total phosphorus present in the water body, history of the water body such as inflows, runoff and sediment conditions as well as chemical properties of water. As a general rule, Phoslock applied at the rate of 100:1, i.e. 100 g Phoslock required to remove 1 g of bioavailable phosphorus (FRP). For smaller applications, the standard dose rate is 200 mg/L, assuming approximately 2 mg/L of total phosphorus in the water body (see Smaller Application Brochure).
