Yeah that should be fine!
I just set my tank up about 9 weeks ago, so my tank is still relatively new as well.
Running chemical filtration during the cycle can just throw it off.
If you are going to run the sponge or fine filter floss, just make sure to clean it about every 7-10 days to make sure its not clogged with a bunch of garbage!
Once your cycled, add all of your filter media right away then wait a couple days to make sure your water quality is where you want it to be!
