10 Reasons Not to Use Copper Sulfate for Water Treatment

Thus, using copper sulfate will create more work in the end. It does not biodegrade. As stated above, copper sulfate accumulates as a heavy metal precipitate once it is applied to water. Because of this, it does not biodegrade. A buildup of copper sulfate can lead to a sterile water bottom, which can decrease and kill beneficial bacteria.
