How to get the best results from copper sulfate in footbaths
The need to mix can preclude its use in an automated footbath system. Copper sulfate is also prone to rapid deactivation when copper ions combine with ions from manure, urine and other organics in the water. Lastly, the price of copper sulfate is currently at an all-time high due to the rebounding economy and other economic forces.
