ewest - do you have a reference that shows chelated copper does not end up in the sediments? Absorption of the chelated copper in the water column does occur either by organics or planktonic organisms until all is absorbed. Bound copper compounds are normally stable in the enviornment and do not normally decompose. They can change chemical states. What is the enviornmental fate of the bound copper from chelated copper products if the end point is not accumulated in the sediments? Where does it end up? As I understand it, the main benefit of cheleated copper products is that one uses less elemental copper per dosage compared to CuSO4 (copper sulfate).
