About this item
  • 【 MONITORS NITRATE IN AQUARIUM AND POND WATER】: Nitrate is produced by the beneficial bacteria in the water and filters as they break down the fish’s toxic waste products (ammonia and nitrite). Nitrate is not typically toxic to fish, but excessively high levels (>100mg/l) can cause problems with growth.
  • 【 EASY 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.
  • 【 WHAT NITRATE LEVELS DO YOU WANT 】: The level of nitrate is dependent on several factors, including the nitrate level of the tap water and the number of fish. High nitrate levels will lead to algal growth. A nitrate level of zero is ideal and implies a balance between waste produced by the fish and nutrients taken up by the plant life. Maintenance of a zero level of nitrate is difficult. Most water supplies have a low level of nitrate. The key to maintenance of low nitrates is regular water changes to dilute the build up of nitrate. Also, increasing the higher plant life in the aquarium should use up nitrate. This will lower the amount of nitrate available to algae.
  • 【 ACCURATE LIQUID DROP TESTS 】: All NT Labs water testing kits are liquid drop tests from a dropper bottle to ensure the drops are the same size. This method of testing is significantly more precise compared to using dip strips. The use of liquid reagents guarantees accurate and dependable results for each parameter, simplifying the process of monitoring and maintaining ideal water conditions in your aquarium.
  • 【 SUITABLE FOR ALL AQUARISTS 】: The ease of use of NT Labs Test Kits means they are perfect for use by beginners and seasoned aquarists alike.
Product description

The NT Labs Nitrate Test provides a simple, easy to use testing kit for determining Nitrate (NO3) levels in both ponds and freshwater aquariums. The NT Labs Nitrate Test Kit comes complete with test tube and liquid reagents to provide accurate results for 30 tests. Nitrate is produced by the beneficial bacteria in the aquatic environment and filters as they break down the fish's toxic waste products, Ammonia and Nitrite. Nitrate is not typically toxic to fish, but excessively high levels can promote unwanted algae growth. What is Nitrate? Nitrate is produced by the beneficial bacteria in the water and filters as they break down the fish’s toxic waste products (Ammonia and Nitrite). Unlike Nitrite, Nitrate is not typically toxic to fish, but excessively high levels (>100mg/l) can cause problems with growth. What is the correct Nitrate level? The level of Nitrate is dependent upon a number of factors, including the Nitrate level of the tap water or spring water used for water changes, the number of fish and the amount of food fed. High Nitrate levels will lead to unwanted algae growth. A Nitrate level of zero is ideal and implies a balance between waste produced by the fish and nutrients taken up by the plant life. Just remember: this plant life does include algae. What do I do if the Nitrate level is wrong? Maintenance of a zero level of Nitrate is extremely difficult. Most domestic water supplies have a low level of Nitrate. The key to maintenance of low Nitrates is regular water changes to dilute the build up of Nitrate.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
