Kent Carbon RECALL!

[Myka]

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...

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.

This is disappointing. I just purchased a pound of this stuff. I've only had it in my system for just over a day. My expiry date is not included in the recall, but as it is an earlier batch than those listed (15oct13 expiration) it makes sence to me that mine could also be affected. I've now pulled it out.

How quickly are the results of the contaminated carbon becoming apparent?

This annoys me. If it is contaminated I can't use it in any of our carnivorous plant terrariums, either (though I have one tropical plant terrarium I could use it in).

My batch date was exc14oct I believe. And I noticed over night. Odds are if you didn't it could be fine. But test your water for contaminants like copper.

FWIW, I have a batch of carbon that is likely from prior to 2010 and well before the recall dates (I think I purchased it in 2010 but it sat in the store for awhile). I started using it late 2010 early 2011. During the past year and a bit of using it my tank has gone downhill. Lots of cyano algae, decline in coral coloration and some receeding and two corals had algae start to grow on their tips, one so much so that I ended up fragging it and disposing of the majority of it. I had no idea what was going on but I because very busy and didn't really have much time for the tank other than basic maintenance so I figured I just needed to put more time into it. After this kent issue came to light, I didn't really think my kent carbon was a problem but decided to switch to ROX for a lark (everyone raves about it). Within 2 weeks my corals were coloring up, those SPS with the algae growing tips were clipped and healed up nicely (previously they would just regrow the algae) and all of my cyano is gone. While I don't know if ROX is the answer I do know that Kent was certainly not. I still have about 2/3 of a 5 gallon pail just sitting here. I'm not sure if I will use it intermittently or just dispose of it altogether.
