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 filter media in your Aqua One Splish & Splash S

Watch the guide or follow the steps.

Aqua One Clear View Hang on Filter · Aqua One (official)
  1. 1Unplug the filter at the power supply and lift it off the back of the aquarium.
  2. 2Remove the dust cover (lid), drain the water left in the filter body over a sink or bucket, and take out the carbon cartridge and the sponge.
  3. 3Rinse the sponge gently in a bucket of aquarium water, only to remove solid waste: Aqua One says never to rinse it with tap water. Shake the carbon cartridge in the same water to flush out waste.
  4. 4Put the sponge back between the carbon cartridge and the front of the filter, or a new one once the old one has worn out.
  5. 5Hang the filter back on the aquarium, fill the filter body with aquarium water until it overflows back into the tank, replace the dust cover and turn it on.

Where can I buy the 25054S in Australia?

How do I fit the 25054S in an Aqua One Splish & Splash S?
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.
