HMMMMM.... I have Kent Reef carbon, but haven't been using it for some time (running carbonless), and my tank was making a comeback. Decided, why not put a little bit in after christmas vacation, and corals started to die. Never thought it was the carbon, but it was the only change, so took it out and I am running carbonless again. RTN has stopped and corals coming to life again.
Now in saying this, my carbon is much older and doesn't fall into the bad batch stated in this thread. Maybe Kent is just BAD!!!
Carbonless is the way to go for me.
