Very tricky especially since we don't know what the ratio of CNP the specific bacteria are using or even what they are for that matter.
You don't need a lot of NO3 and I would be very reluctant to dose it though I do have some old bioballs I could use. Reef surface waters run at around 0.2ppm NO3, so I wouldn't worry much about a nitrate deficency unless true 0 levels were reached which is ,in my opinion. unlikely in a reef tank that receives some food/ waste.
Careful testing/monitoring would be a must. Too much nitrate along with the carbon dosing could lead to chaotic bacterial blooms.
