What do you think?

I would follow the steps I outlined, and if after several weeks you are still getting Cu showing up I might change them out. I think right now it is a big cost and disruption to your tank. You will need to change them all out at the same time, so I would be trying this as a LAST resort. I really think those products are promising, even for your rocks.
