I started a thread earlier about media. After reading some more, I think I understand. The light bulb went off! I have kept tanks for a few years and have done the wc and used carbon but never really understood why.
The filter is used to clean the "larger" stuff out of the water and to "store" bacteria that turns ammonia into nitrites, nitrites into nitrates. Water changes & vacuuming get rid of the dead stuff & nitrates, which live plants can do to some extent as well (nitrates).
It doesn't really matter which choice of media as long as it has a large surface area to hold the bacteria and is rinsed then replaced from time to time, being careful to always keep some of the media so that you do not break the cycle in the tank.
Keep carbon on hand in case it is needed to remove meds after treating the tank but is not necessary day to day.
Does this sound about right? Did I miss anything?

It took me long enough.
