Copper safe ?

[p fish]

I keep cooper safe in my hospital tank for my new fish. My question is I went to my LPS and the guy there told me there is no difference from salt copper safe and fresh water copper safe. Is this true or is my LPS guy blowing smoke once again....thanks.

I live in a area where I can't get much during the week and my LPS is very limited, but I will check into this on my weekend Pet Store travels.....thanks.....still I have the ? is saltwater copper the same as freshwater copper? Just want to see if this guy is as full of it as I think he is.
