I have been running carbon 24/7 since setting up my reef nine months ago. About a month ago I accidentally turned my carbon off for a week and ended up getting some STN/RTN. Once I turned the carbon back on the TN started to clear up and are all completely healed today. I'm a strong believer in carbon now :-)
