I can't remember where I found the info, but it made me rest easier as I didn't want to ruin the tank for future use.

My 110g tank had cupramine in it and I use it now as my mixing tank for water changes. I don't have a lot of inverts but my hermit crabs, nassarus snail and sand sifting starfish are all fine and I've been using it for water changes for a year now. No adverse effects as of yet as far as I can tell.
