Green rust = copper?

[gregzz4]

Green corrosion indicates copper-based material

And pretty much only copper right?

[FitoPharmer]

I guess that is why they have not had much luck with inverts to this point.

[gregzz4]

Copper-based includes brass and bronze
Silver- and chrome-coated copper-based material will also do this if the coating is compromised
Regardless, it's not good
Might be hard to get a reading, but it wouldn't hurt to run a copper test

[FitoPharmer]

I might run a test now that you brought that up. Thanks.
