Can you provide any pictures of what happened? Has any other testing been done to confirm this?
I should have taken pictures.
It took several hours of Distilled vinegar/Hot Tap water to clean off the black residue. Which covered the entire block.
Still there is some staining. I didn't want to use any abrasives because of the Micro Channels.

My entire loops consists of Copper, Distilled water and a Silver Coil.

Though for second opinions ask NaeKuh.
