Removing meds question

[Where the river goes]

How long do you usually leave carbon in the tank to remove medications?

Very good question that I can find no real answer for! I would think a day or two, but I'm not sure. I usually just remove meds with water changes.

If you regularly use carbon in your filters, then keep it in until it's due to be changed. If you are only using it to take out the medications, then keep it in for about a week. Did you know that if carbon isn't changed regularly, it will leach the toxins that it's gathered back into the tank after a few weeks.

I don't normally use carbon in my filters, just to take out meds. I'll probably just do a large water change though.

Yeah, I knew that when I do use carbon, it's only in there for no more than 3-4 days. Thus, I'm realizing, it's just best to do water changes.
