Buckets /Water & Copper ?

[1boatnut]

Just want to hear some thoughts.
I purchased some new fish yesterday and used my buckets that I mix my salt in to acclimate these fish. The water from the store has copper.
Are these buckets no longer usable for me to put ro water in and mix my saltwater?

I've heard both sides of this argument what seems like a million times. I have decided to believe that plastic in all forms is porous enough to absorb copper and leach it out later. I know that isn't the conclusive answer you were hoping for, but now I get to here it for a million and one times.
