I lost for around 700$ in corals and my carbon is not in their list of recall! Yet I have the professional laboratory analysis that prove that the carbon is contaminated with copper and nickel as well as a higher than normal content in arsenic.

So water change 30% each day or every second day (age the water for 24 to 48 hours) and use polyfilter to remove the contaminant. It does not take a lot of copper to kill everything.

I gotta ask. You took your carbon to a lab for testing? This must have been costly. Where do you even find a lab who takes stuff from a person "off the street"?

I would think most labs are closed environments.

The chemist that is the leader of the metal testing department is also a marine aquarist and a member of our forum, Reefaction. I already had the contact to the right person. This is a huge laboratory located in MOntreal. I may have made a mistake in the name before but it is called Maxxam laboratory: http://maxxam.ca/ They have millions in equipement When I went to bring the samples, they gave me a tour of the place and it was very impressive!

As for the cost, it was minimal since I only paid for the actual cost of the test, so it was well worth it to find out what was in that carbon before I sent it back to the company. They only tested it for metal.

I wanted to confirm that my case was a case of copper or what ever contamination and not something else like coral war or anything else. I also wanted to have my current aquarium water tested to make sure I did not have any more copper in my tank after all these mesures and I was relived to find out that no more copper was in my tank. I did it for my peace of mind.

Then I sent a sample to Kent Marine so they could test that batch too. They should receive it somewhere this week.
