You talking about Rox? Never heard of this carban, where can I get some in Calgary? I use Kent, as I can get it, been trying for some time to get the Zeo Carbon (expensive, but wanted to try it), but it has been backordered everywhere forever.

I like to refer to this blog post when it comes to Carbon related matters.

Good link. I have always thought similar and still do. I recently took advantage of some bulk carbon sales at BWI. Bought another 5 lbs. Also use Black Diamond regular and purchased some carbon pellets from BRS to give a try with.

I run both passive and in a reactor but dont see much difference as the article states. Large difference with gfo but not carbon, at least IMO.
