Using carbon to remove meds

[JRT83]

Just got done dosing my 125 gallon tank that houses my 7" jaguar cichlid with tetra parasite guard and was wondering if I need to add carbon to all 3 of my filters or if it would be ok to just add the inserts to my 2 biowheel 350s... other filter in question is an aquaclear 110. Do I need to add carbon to that also or will adding new inserts into the biowheels, while leaving the old filter cartridges containing the beneficial bacteria, be enough to remove all the medication from the tank?

well as suggested with most meds there is supposed to be water changes done after medicating and that will remove a lot of medication. just add some to your 350s and u will be fine

I changed about 33% of the water last night, how long do I need to leave the carbon in? I don't generally use carbon in my filters and am not sure how long it takes to remove meds from 125 gallons of water
