How to change the A495 aquarium filter media
Watch the guide or follow the steps.
- 1Unplug the filter and lift it out of the aquarium.
- 2Open the filter and slide out the foam pad and the cartridge (U2 to U4 also hold BIOMAX).
- 3Rinse foam in water from the aquarium; rinse BIOMAX in aquarium water only: Fluval says never to rinse it with tap water.
- 4Fit the new BIOMAX in its compartment. Fluval says not to replace all filter media at the same time, so the bacteria on the other media carry on.
- 5Close the filter, put it back in the aquarium and plug it in.
