We should be carefull not to point every possible crash on Kent carbon, as there might be other causes. The only way to be sure is to do a test and let a cup of carbon run into a bucket and then test for copper. If there is no copper than the carbon is NOT contaminated.

I didn't say it was a crash. Nothing in my tank died, it just went downhill and I had some cyano issues. I don't have a copper test kit. When I find one I'll do the test but for now all I can do is suggest that perhaps Kent was the problem. Who knows, perhaps it wasn't copper but something else?
