Need help EK Nickel block problem!!

[blazekick]

This block is only one day old in my loops but it looks terrible. Everything else in my loop is copper and no see any trouble for 5 years. 

ps: I have a silver kill-coil.

If you have any nickel in the loop a silver kill coil isn’t recommended because in a loop environment they are borderline dissimilar metals. It will corrode the nickel plating, you are best off with a premixed fluid that has both biocides and anticorrosives such as Mayhems X1 or EKWB cryofuel.

Like said silver and nickel won't play well together at all.
