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.

Reset your filter change indicator each time you replace your filter: To reset, press the âRESETâ button (on some models called the âSTATUSâ button) below the lights on the indicator. Release the button when the green light blinks.
