Keep in mind that numerous years and years of treatment with CuSO4 loads the sediments with a precipitated bound form of copper carbonate a form of heavy metal. As this accumulates toward saturation level, the health of the sediments will be compromised. You may not see apparent negative effects soon but the next owner my see the impact. How can pond sediments be considered healthy teaming with invertebrate life when they are loaded with a chemical complex form of metallic copper at hundreds if not thousands of times greater than normal soil?
