I just bought a 55-gallon tank that came with a Whisper 20. Since I want to try planting this time around, I want to take out the carbon media and replace it with a cut-up sponge that can hold bacteria.
The idea is to be able to replace/clean a sponge section from the bottom and add a new one to the top as I do a partial water change.
I know I'll need another filter for a tank this size but this seemed like a good chance to experiment since the filter came with the tank and I have no use for activated carbon.
