you never had issue but obviously a lot of people do, even those have have been using this carbon for 7 years like that store owner.
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.
