Kent Carbon RECALL!

paddyob · #1 03-17-2012, 06:13 PM

I think it was posted a while back.

Yeah man, read the bottom part of my message. "Nano" just used some Kent Carbon on his reef tank and is seeing the effects as we type. Obviously the recall alert is being overlooked because it is hidden in a thread with an unclear title and many pages of jibba jabba before the problem was identified. This thread is to make the recall alert more obvious.

yup dont use it! My montis looked slightly bleached too, hopefully there is enough tissue alive to bring them back!

I think in your case the carbon was a false-alarm and there might be other issues you should be looking for.

could be, but its sure weird that my parameters aside from my alk(which is usually high) are ok, that the only change I made was adding the carbon then today everything is looking like crap

no, I think the carbon did cause it. Not all contaminated carbon is in that recall list, as I posted this warning and many threads, so just don't assume that because a certain batch is not in the recall that it is not contaminated.

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.

Thanks for clarifying Daniella, that is not good that there are affected batches that are not on the recall list.

That's enough to stop me from buying Kent Reef Carbon! Wow...

subman · #8 03-18-2012, 04:49 AM

that's enough for me to stop buying kent all together!

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.
