Does carbon bleach your corals ? (Kent carbon recall)

[globaldesigns]

HMMMMM.... I have Kent Reef carbon, but haven't been using it for some time (running carbonless), and my tank was making a comeback. Decided, why not put a little bit in after christmas vacation, and corals started to die. Never thought it was the carbon, but it was the only change, so took it out and I am running carbonless again. RTN has stopped and corals coming to life again.

Now in saying this, my carbon is much older and doesn't fall into the bad batch stated in this thread. Maybe Kent is just BAD!!!

Carbonless is the way to go for me.

You know, you just reminded me that I ran Kent Carbon once back in 2010. I had forgotten about that till now. It was only 1 container of Kent Carbon before I switched to ROX that I'm using now. However, while thinking back, the time I used the kent carbon may have been close to the time I had my major SPS die off in 2010

!!!!!!! Could be!!! And what really sucks is I see when things started declining, you put in MORE carbon!

You are right, I used to put more carbon when something happens and I thought there is a poluttant in my tank. What a stupid thing I did in the past !
So no more carbon for me like globaldesigns say.

Ok...I was not dreaming. There was no possible other reason for my tank crash.

But I do want to be refounded for the loss of some of my corals. I surely hope they will refound that. I don't know what they will do for the store owner who lost 10k in corals??

Mine is also from that bad batch. It really upset me when I think that I was trying to do the best for my reef by putting fresh carbon, and that killed my most precious corals

Big lesson learned, never ever use carbon that is mined ever again. I will only use things like polyfilter or similar, never use carbon again.

That's almost ironically funny.. in a sad and depressing sort of way..

Yeah, who woulda thought! The past couple years of coral issues, massive die off, and loss of $$$$... And maybe it was the Kent carbon all the time. I never thought carbon would be the problem, and have used Kent almost since the begininning.

I am not even going to bother with ROX, or a higher quality brand. Carbonless seems to be working for me, and I am really tired of losing coral, so I am going to leave it as is.

And not necessarily Kent alone. If I recall correctly, Coral Master/Snappy had a major SPS die off event a couple of years ago as well and the only thing he recalled switching up was trying some new carbon that was on sale on Boxing Day that winter. If it can happen to Kent carbon it stands to reason that it could happen to any carbon produced in a similar fashion ?!? This would explain so much! That is, you could be using carbon happily for months or years and then just happen to dump in a bad batch out of the blue!

The one good thing that has come out of this in my mind is the fact that Kent owned up to it an explained clearly exactly how carbon could be eff'ed up! If they had not come forward to acknowledge fault we'd still be scratching our heads and would probably never think to blame carbon for our woes. Unfortunately I'm worried about all carbons now :-|

I wonder if Seachem carbon is manufactured the same way and if it run the same risk?

It is very scray and disapointing

The whole purpose of carbon is something we trust will remove contaminants from our tank, not to contaminate it more to the point everything die.

I don't think that it'll be easy to tell if a particular batch of carbon is good or bad

Another thing I'm worried about now is, once you put bad carbon into your tank, how easy would it be to get all that nasty stuff out??? It's almost like you have to flush the tank just to be sure.
