Yes, put them back in; as Tizer says they're just black not carbon. Are they cycled though? Rams are very sensitive to water quality; you really need to get some mature media running in that tank, ASAP.
If you've got mature sponges or ceramic rings in another tank, you can make a little box filter using an old coke bottle or something like that and run it off your air pump..
