Definitely darker than 40, maybe not quite as dark as 80, but certainly not between 40 and 20. That's what I'd shoot to get after a water change.
Nitrate isn't very dangerous to fish, but it's not good to have them swimming around in high concentrations all the time. In aquaponics I tried to keep nitrates near 60- enough for the plants, but certainly safe for fish.
