1. Rinse the test vial with the water to be tested.
2. Fill the vial to the 5 ml mark with the water to be tested.
3. Hold the bottle containing test reagent 1 upside down over the vial and add 14 drops.

11. Allow 10 minutes for the colour to develop. (The powder sinks to the bottom.)
12. Hold the vial around 1 cm (finger‘s width) in front of the white surface of the colour chart. Match the shade of the test solution to the colour it comes closest to on the colour chart and read the corresponding value. After each test, rinse the vial thoroughly with tap water.

Values and assessment

Optimum nitrate values:

• Freshwater aquarium: < 50 mg/l
  

• Marine aquarium: < 10 mg/l

• Pond: < 10 mg/l

What should I do if …
… the nitrate content is too high? – Carry out partial water changes (30% each) until the nitrate content is less than 50 mg/l. Remove any dirt, such as plant and food remains. Before adding new tap water, treat it with Tetra Aqua Safe to make it safe for fish.
Advice: use Tetra NitrateMinus regularly in freshwater aquariums or Tetra NitrateMinus Pearls in marine aquariums. Ensure lush plant growth with Tetra PlantaMin, because plants remove nitrate as a nutrient from the water. To maintain optimum water quality we recommend that you check water values weekly. All Tetra Test products are easy to use and very accurate. They use professional methods to determine chemical water values. Available for all key water values.
