MasterLine Nitrates is a macronutrient fertiliser containing nitrogen in the form of nitrates and additional potassium. Nitrogen is a main nutrient of plants, which is essential for healthy plant growth. In aquariums, nitrogen deficiency is often caused by denitrification processes. This can be prevented by fertilisation with MasterLine Nitrate as required.
MasterLine Nitrate can be combined with all other single component fertilisers of MasterLine or can be used in addition to complete fertilisers like the MasterLine All In One in order to specifically adjust certain nutrient levels.


  • Nitrate fertiliser with additional potassium
  • Supplies the aquarium plants with the most important macronutrient nitrogen
  • Promotes lush plant growth
  • Prevents algae growth
  • Combinable with MasterLine single nutrient fertilisers or complete fertilisers



1 ml MasterLine Nitrate per 30 litres of aquarium water adds the following nutrients:
NO3 1 mg/l
K 0.63 mg/l

MasterLine Nitrate is dosed as required if the nitrate concentration decreases below 5 mg/l.
The recommended dosage is only a guideline. Depending on the aquarium, the dosage of the fertiliser can be reduced or increased to achieve optimum results.



Shake bottle well before use. Store in a cool place without direct sunlight.
