Using Carbon to remove medication

Hello,

I had to use a parasite removal agent in one of my tanks, and now I'm curious about using activated carbon. I must admit, in my many years of fish keeping, I have foregone using meds, or carbon preferring a natural approach of using water changes. As this didn't work with one of my prised Geophagus, I decided to use the advise of a couple importers and dose metronidazole. I was quite surprised to see some fish that looked perfectly healthy have some clearish feces one I started dosing, and now feel confidant I am on the right path.

My question has to deal with once im done all this, do I have to put the carbon in the filter or can I just put the bag in the tank so that it floats around.

Looking to hear what works for people.

I expect that adding it to the filter would be the fastest and most effective way of removing the medication, or at least setting the carbon near the output from your filters. I'm sure that just sitting a bag of it in the tank would absorb some, but I'm really not sure about the time frame for that.

It has to go in the filter.
I've never used carbon to remove antibiotics - just for dyes. I always approached antibiotics (rarely used, like you) with massive water changes after. Then again, I passed on using carbon with no reason I can think of.
