Consequence, stagnation or lack of growth of your corals.
The optimal values of NO3 by type of population are:
Thanks to Nitrat plus, easily and quickly adjust the desired NO3 concentration
1 ml of Nitrat plus increases 1 ml of NO3 per 100 liters of aquarium water
For any significant increase, take steps over several days.
To maintain a stable NO3 level, we recommend additions by GROTECH dosing pump in daily intake
