It went away a week after he switched brands.

Did some reading on carbons based on Greg's experiences, in one of the threads discussing it, there was a link to a discussion about carbon available from BRS labelled "ROX 0.8" .. long story short, it sounds really good. I went and ordered two packages for myself already..

ROX 0.8 is great Carbon, I have used it myself. We have access to this carbon as well as lignite which is also almost as good.
