How to change the 25322C aquarium filter media

Watch the guide or follow the steps.

No clear video for this part yet. The steps cover it.

  1. 1Unplug all the aquarium's equipment, then lift off the light unit and lid and put them somewhere safe.
  2. 2Open the filter compartment and take out the sponge and the cartridges (carbon, and ceramic if your tank has one).
  3. 3Take some water out of the aquarium and rinse the sponge and cartridges in it. Aqua One says never to rinse the sponge under the tap, as that kills the beneficial bacteria. If needed, siphon waste out of the filter chambers.
  4. 4If the carbon cartridge is due for replacement (every 6 to 8 weeks, Aqua One says), throw it away and fit a new one.
  5. 5Refit everything, replace the lid and light unit, check your hands and plugs are dry, then turn the power back on and check the equipment over the next half hour.

How do I fit the 25322C?
No tools, a few minutes: 5 steps, listed on this page with the replacement video where the maker has one.
What happens if I don't change it?
Spent carbon stops removing odours and discolouration, and clogged pads slow the flow, so the filter moves less water through the tank.
