Effect of Copper on Reef

[Gizmo]

I can tell you first hand that copper will wipe your system dead. It will kill your inverts as stated above, your rock, and eventually your fish. (even though a copper dip is used to eliminated some fish disease). luckily for me it stoped at the fish, but I lost almost everything else. Get some cuprisorb if you think you might have some and get it in your sump.
