well i never used it for the first couple years i kept sps and never had any issues with yellow water or chemical warfare or whatever and that was in a 25g tank.

that's why i originally posted this question...because i really don't see any tangible benefit. with regular water changes, i never got yellow water anyhow. so am i just wasting time and money by the adding carbon?
