copper

[reefnut]

when i first started up my 48 gallon tank i had planned on fish only.So when i got my damsel and my firfish i added the water that was in the bag to my system.Same deal with my copperband and my valentini.I would say that ive added 1-1 1/2 gallons of lfs water to my tank.My question is with all the water changes ive done would there still be enough copper to be killing my polyps?If so does that mean i should not use the lr out of that tank for my beginners coral tank?

IF there was copper in the bags, I'd personally not use anything it touched for inverts. Maybe confirm with the LFS that they use copper, and maybe do a test.
