If the first filter is working and the tank is fully cycled then adding another filter and running them together will not disrupt the cycle. If you plan to remove the 2nd filter then it should be left a good couple of months to let the new filter get a full bacteria colony. My advice would be to keep both filters, firstly you can never get enough filtration, secondly its a great backup if one ever breaks.
