How to change the 25035C aquarium filter media
Watch the guide or follow the steps.
- 1Unplug the filter and any other equipment in the tank, as Aqua One advises and lift it out of the tank.
- 2Pull the filter casing off the motor and take out the sponge, and the carbon cartridge or pouch if your filter has one.
- 3Rinse the sponge gently in a bucket of water taken from the aquarium to flush out solid waste, then throw that water away. Aqua One says never to rinse it under the tap: chlorine kills the filter's bacteria.
- 4Fit a new carbon cartridge every 6–8 weeks, or sooner if needed. Rinse a new one first; tap water is fine for new carbon, with no detergent or soap.
- 5Put the media back in the casing, refit it to the motor, put the filter back in the tank and plug it in. Check that water flows.
