I'd use RO water with the peat moss. You might also consider buffering with Seachem Stability to ensure consistency.
Starting with a known (the RO water) is a much better way to ensure consistent water parameters from water change to water change. Otherwise you possibly could end up with dramatic differences between water that's been sitting in this setup for one week versus two, three, etc.
Unless you're setting this up to breed something, it's probably unnecessary.
