Back around thanksgiving i bought a new filter because mine burned up. The new one came with a bag of carbon and a foam block. I added my old(established) media and everything is good. Yesterday during my water change I swished the media in the old tank water and put it all back in order. Afterwards I got to thinking: how often, if ever, does the baggie of carbon need to be replaced? This is my first time running carbon in a filter. Thanks.
