There is no set rule for when your need to replace filter foams in aquarium filters, however, there are some signs such as dirty water circulation, poor water quality and reduction in flow from your filter that help indicate when this needs doing. Although a foam may look fine in appearance, it may have shrunk over time allowing debris to pass this stage of the filter so its advised always having a spare handy to compare.
