Depends on how much you use
Depends on how heavy the DOC's are in the water colum as well as minerals and other dissolved solids in the water.
Could be 2 days, could be a week, also depends on the brand of carbon that you are using. Most reefers will change the carbon often.
Those who run ozone will run with carbon 24/7.
FRom most of the reading I have done and the vast use of cabon that I have used, I would say a month isn't very realistic.
2 days to a week at most for many carbons.
