I'm sure with all of the minerals and elements in the earth copper would be present in the ocean to a small degree. Don't forget, even in humans, many substances are safe, some even beneficial in small doses, but toxic in heavy doses.
I have been in so many discussions over tanks and copper, it is rediculous. Not ONCE has the opposing view to my beliefs that this is a myth come up with a single fact or proof, to prove me wrong.
Here is my belief.
You take a tank that has been treated with copper, then after the treatment, remove said copper with Polyfilters or whatever your preferred means. The so-called experts will tell you the silicone has absorbed the copper and it will leach out forever.
The copper that is "supposed" to be leaching from the silicone
is NOT a renewable source, so if it leaches out into the water column, it should be removed by water changes.
As I said, not one person on the opposing side of this debate has ever given any proof other than to say, "this or that died in my tank, and it had copper in it at one time". I guess it is impossible to think anything other than copper could have been the cause of these deaths, as we all know, everything survives in our tanks forever, right?
When asked for proof on my end, I just have to send a pic of my tank, it has had copper in it on a couple of occasions and my corals, inverts and fish are all alive and well. I can even go one step further, I have old coral skeletons in my tank now that were previously in tanks treated with copper.
