I am not sure if there is a rule of thumb about how much carbon but I usually throw about 1 litre into a media bag in my 230g and the same for my 190g. I remove it after a month although I have heard that the actual value of the carbon is lost after only a few days (or it could even be hours - I can't remember right now).
