COLOMBO - Nitrite Test - Analysis of Nitrite NO2

The Benefits of Colombo Nitrite Test

Accuracy and Reliability The Colombo Nitrite Test uses a drop method, which is known for its high accuracy. This accuracy is crucial because high nitrites are dangerous to aquatic life. With this test, you can detect even the lowest levels of NO₂ and take the necessary steps to protect your fish and plants.

Easy and Quick to Use With clear instructions and a color chart, the Colombo Nitrite Test makes analyzing your aquarium simple. Even beginners can perform this test without difficulty, allowing for regular and stress-free monitoring of nitrite levels.

Essential Monitoring for Aquarium Health Nitrites are a key indicator of water quality in an aquarium. Frequent monitoring with this test allows you to react quickly to any increase in nitrites, thus avoiding health risks to your fish, especially after the introduction of new occupants or in the event of an ecosystem disruption.

Economical and Sustainable Solution The kit offers 40 tests, making it an economical solution for aquarium owners. It allows for sustainable and regular monitoring, essential for maintaining a stable and healthy aquatic environment.

How to use the Colombo Nitrite Test?

General instructions

• Always make sure the test tube is thoroughly clean before use.
• Clean it thoroughly after each use so that it no longer contains any chemical residue that could distort subsequent results.
• Take the water sample as carefully as possible.
• Hold the vial upright when counting drops.
• Make sure there are no air bubbles in the drops.

Test procedure:

1. Take a 5 ml water sample.
2. Add 5 drops of NO2 test liquid.
3. Shake the test tube.
4. Wait 5 minutes.
5. Determine the NO2 value of the water using the colorimetric card.

To judge the colour of the water sample after all the test liquids have been added, proceed as follows: Place the test tube on the colour card supplied with the kit and look simultaneously - from above - into the test tube and onto the card. Do not look under direct sunlight, but under indirect light. Compare the colour of the water sample with the colours on the card. The colour that matches best indicates the desired value. The colours of the sample and the card are not always identical, as the actual values are usually between two standardised values and therefore correspond to a mixture of two adjacent colours. In this case, it is necessary to judge approximately between which colours the sample actually lies.
