Thanks again all! :)
If you run them, two weeks minimum, turn off the old, test the water after a few hours. If ammonia and nitrites are zero, test again in a day. If still zero, good to go. If it rises, turn the old back on for a few more days to a week as the new may not be established yet.
Repeat until you get good results without the old one running.
