What is the best nitrate range for a reef tank. So many different sources I’ve seen <1ppm, 5-10ppm,<2ppm, 10-15ppm. Mines currently near 0ppm. Should I keep it there should I bring it up to like a 5ppm. What is your current nitrate levels and what’s you success with it? Does any one dose nitrate, should I put more fish in?
