A large percentage of the copper, because of its density, ends up on the bottom of your pond. This leads to sterilization of the most important part of your ponds ecosystem, the bottom.

The solubilization of copper precipitates allows it to continuously impact your pond's ecosystem, especially bottom dwelling organisms. Copper precipitates will also enter the water column through solubilization.

In other words, once you put copper in your pond, you might as well name it because it will be there affecting your pond longer than you will.
