Run Carbon Intermittently ?

[Dez]

+1 on Wes' comment. I'm on ROX carbon and I use very little (1 cup) in my system (approx 340 gallons water volume) and it seems to me that my water is pretty clear. When I siphon water out into a white pail, the water is still clear and not green like my old systems were without carbon. I haven't lost a coral yet *knock on wood* and the system has been up since Aug 09.
