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]

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

no doubt. I'm taking mine back obviously hopefully picking up some of that polyfilter myka mentioned and hope it fixes the problem. I think the chemi pure elite is enough for a tank my size anyway, especially with a refugium packed with chaeto and macro algae

I picked up carbon last weekend, but due to these threads, haven't used it although it's not Kent. Is this just limited to Kent carbon, do they produce for others as well?

I have had lots of coral loss over the past 2 years or so, and could never figure out why. I have been running carbonless until recently with greater success. Put some kent back in after christmas and again major RTN, removed the only change being the carbon and rtn stopped and coral is doing great again. Never thought of carbon as the issue, but I have always used Kent... never again, and I recommend others dont either.

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.
