I did contact them today and waiting for their response.

In any case, this is super easy to prove...the proof is in the pudding. I do have the carbon with me. The store owner has sent some of the carbon to kent marine for analyse and we should soon find out what is causing havock with this carbon.

Kent Marine is aware of the situation and they will surely ..well hopefully do something about it. I will post their reply here once and if they do reply.

So far I have about 2000$ loss in coral :(

Probably not all of Kent carbon is bad, but probably some batches are contaminated with something. Since people from NY are experiencing the same thing, I am guessing it is far more spread than you want to say. I live in Canada, not in the USA so some bad batch could be in the USA and in Canada and possibly elswhere.

Even if this was a false alert and everybody having issue are just dreaming a bad nightmare, it is better to be safe than sorry and not use this carbon for now.

I still cannot believe what happened to my tank, because Kent carbon was my favorite for so many years. It is so sad :cry: !!I didn't loose $2,000 on corals like you, because I only pay $10, $15 for a frag, but to see them growing up and colored up with joy everyday, and now look at them dying from bleaching, it really breaks my heart :cry:
Please update if you get any more information from Kent. I should have kept a small sample from that bad carbon and send it to the Kent company to verify that I was not wrong.

I have plenty of this bad carbon left. Don't worry, they wrote in the other thread that the store owner have sent a sample to the company. I am keeping mine for sure, in case there is a need to analyse it.

I guess the important thing is to have proof of purchase if you don't have any carbon left.

I lost 2000$ worth in coral. That's the price I would need to pay to replace what I lost. I too started a few of these pieces with little frags but they were no little frags anylonger so they are not worth 30$ any longer. Even if you bought your corals are 10$ frag, they are worth a lot more when they grow large. It is that cost that you must calculate because replacing those pieces would cost that much.

I also had the sme issue when I switched to Kent, 1 afternoon I switch out the carbon, next morning serious colour loss. I simply turned off my carbon reactor, reduced my light duration, and kept a watchful eye.
Non of my corals died, but some where looking pretty stressed, no polyp extension, complete colour loss, small amounts of tissue recession.
But in a couple weeks things started to turn around, colour returning, polyps coming out. Now 3 months later everything is growing so fast I cant keep up, my colour has never been better, it crazy.
