Biological filters: Replace the carbon when the aquarium water turns cloudy, or at least once every two months. Chemical filters: Give the chemical filter a good cleaning out when it appears to be clogged, malfunctioning or working very slowly. More frequent cleanings may be needed if your fish is sick.
It doesn't have a battery filter change reminder but you can sign up for email filter change notification to change your water filter every 6 months. Two of the filters ($45 for the two filters) need to be changed every 6 months while the reverse osmosis filter ($59) should be changed once a year. The biggest complain I have heard about these reverse osmosis systems is that it appears that a lot of waste water goes down the drain.
