Kinda, its normal to see when nutrient levels are elevated which occurs a lot in New tanks due to New or old die off in the rocks. Once your tank becomes more established around the 6 months to a year mark then it would be a bad sign that you are feeding to much, not doing enough or big enough water changes, rodi
filters going bad, etc. I would just make sure you keep on a good water change schedule and don't overfeed and your tank will balance out just gotta be patient. Only bad things happen fast in saltwater.
