I have just replaced my tropiquarium 68 with a Fluval 1000 that has a Fluval3 filter
the filter doesn't seem to have any carbon in it - just 2 big plain sponges.Am I missing something .Also unlike the bio life filter in my tropiquarium it doesn't produce load s of bubbles just pushes the water around - is this still oxygenating the water
