I'll answer for Andrew since he's probably busy taking care of his tank! According to the Zeovit method, they recommend running carbon passively (NOT in a reactor) and kneading the carbon daily. Zeovites (people who use Zeovit, I guess) feel that too much carbon activity is detrimental so that is why they recommend passive carbon usage. When I was running Zeovit I put the carbon in a bag at the top of my Zeovit reactor, since the reactor only ran 50% of the time, and I just used less carbon than recommended. I seemed to have good results.
wow, thanks for the detailed explanation. ill be running full zeovit too. bob never mentioned anything about an advantage on running carbon passively. I even asked him explicitly if i could run carbon in a reactor. the only thing he said was that if you'll be running carbon in a reactor while using the zeo method, you would have to use 50% of the recommended amount of carbon for your tank as per zeovit recommendations. of course ill be using KZ carbon as andrew is also using atm.
