NTLABS - Nitrate Test Kit

How to use?

• Ensure the test tube is clean.
• Take a 5 ml sample of water into the test tube.
• Turn the Nitrate-1 bottle upside down in plenty of light and shake vigorously until there is no sediment on the bottom.
• Add 6 drops of the Nitrate-1 and 6 drops of the Nitrate-2. Replace the test tube cap and shake thoroughly.
• Wait 10 minutes, and then compare the colour of the sample to the colour scale provided. Zero nitrate is represented by a colourless sample. Any hint of pink in the sample indicates the presence of nitrate in the aquarium.
