Hi, we've just upgraded from a fluval 90 to a 200. It comes with an external filter with a few trays of media. Theres the big flat poly type scrubbers, 2 trays of bio rings and two smaller trays of carbon.
Do i really need to use the carbon? Or should i replace it with something else, i thought carbon was for removing meds?
If I should replace it, with what?
I currently have 3 fluval 2+ internals running while it all gets settles, and then I will transfer the nicely cycled media into the 205 external.
Thanks
