Kent Carbon RECALL!

[Enigma]

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).
