Salifert Nitrate Test

The Salifert Nitrate Test is a simple and easy-to-use droplet test.

Information about the water test:

• Measuring range: 0.2 - 100 mg/l nitrate
• Gradations: 0, 2, 5, 10, 25, 50 and 100 mg/l
• sufficient for 60 tests

Where does the nitrate in my aquarium come from?

Nitrate is usually introduced through feed. But dying organisms or contaminated and unfiltered water can also lead to an increase in values.

Why is the determination of nitrate important?

Both an oversupply and an undersupply of nitrate can have negative effects on the animals you care for. Nitrate can be absorbed particularly easily by algae and can therefore lead to unwanted and excessive algae growth. This also applies to the zooxanthellae of your corals. Due to the increased nitrate concentrations, they begin to multiply quickly and compete directly with the coral for important substances and compounds. This ultimately leads to your corals growing more slowly and their tissue turning increasingly brown. Your nitrate concentration should ideally be in the range of 5 to 10 mg/l.

If your nutrient concentrations exceed the specified values, you should take appropriate measures to reduce them. If, however, they are below the detection limit and your corals are already showing signs of deficiency, you should add nutrients.
