Dump your old carbon and go get this...

[Tracey2]

I hope I can ask here, how are you guys running your carbon, how much per gallon of water. I have some in a bag in a small reactor but it doesn't seem to do much, its not the rox brand and maybe the fact that it is in a bag instead of tumbling? Also I was consider adding ozone to my tank and was told running carbon properly is just as good, any thoughts.

Thanks for the tip on the rox, I am ordering from there this week.
