How long it lasts
Replace it when it clogs, breaks down or no longer holds its shape, Aqua One says; until then rinse it in a bucket of aquarium water each time you clean the filter.
How to change the 25001S aquarium filter media
Watch the guide or follow the steps.
No clear video for this part yet. The steps cover it.
- 1Turn the power head off and unplug the aquarium's equipment.
- 2Remove the lid from the filter unit and lift the elbow and spray bar off the top of the power head.
- 3Take out the carbon cartridge and the black filter sponge. Rinse the sponge in a little aquarium water in a bucket, then throw that water away rather than adding it back to the tank.
- 4Put the sponge back, or fit a new one once the old one blocks up or breaks down.
- 5Refit the spray bar with its holes pointing down onto the carbon cartridge, make sure the tank is full, turn the power head on and check that water flows from the spray bar. Close the lid.
