I want to medicate my tank but the filter I have only has an insert with active carbon. I got it secondhand and the other more wooly or spongy part isnt there.
If I remove the cartridge I'll lose all my bio. If I keep it I'll lose my meds.
Now one cartridge is pretty old, so would that carbon be like useless at this point and it would be ok to medicate with that one or not?
I'm tired of losing fish.
