Instructions
Unplug and open the aquarium filter to inspect the filter cartridge. The lifespan of a filter cartridge varies based on factors such as the size of the aquarium, number of fish, types of food offered as well as the model of the filter. Filters that are discolored and saturated with organic debris should be changed immediately.
Remove the filter cartridge from the filter box. Keep an old towel nearby to prevent spilling water around the aquarium since the filters are often saturated with water.
Place the old filter cartridge in a plastic bag and dispose of the filter. Filter cartridges that contain organic matter can generate a foul smell quickly once they are removed from the filter. Wrapping the cartridge in a plastic bag helps control the smell.
Rinse the new cartridge under lukewarm water to remove any loose materials before installing it in the filter.
Refill the water level in the filter and secure the top before turning the filter on.
