Carbon Cycling Question

so I have a tropical aquarium with live plants & snails. It is fully cycled, and has been fully cycled since November! I have an aquaclear filter with the media it comes with (mechanical, carbon, and biological) I was wondering if I throw out the carbon packet and replace it with more biological/ mechanical media will it crash my cycle? I know carbon can be bad for the fish once it starts going old, but I'm afraid if I throw it out I will ruin my cycle! ( does beneficial bacteria even grow in the carbon packet? ) thank you in advance!!

carbon isn't really bad if left in the filter, it just has a limit for its intended use which I think is a few weeks. If left in, it'll just be another piece of media for bacteria to live on.
