Nitrate Test Kit - 60 Tests

2 Reviews


Salifert test kits are the epitome of accuracy and precision. Their wide range of available tests have all been designed to detect the smallest traces of certain elements, without interference from other chemicals within the water. Simply put, these are the best test kits you can buy- hands down. The sharp, contrasting color changes make results easy to read so there's no second guessing. Trust your aquarium to Salifert.

Precisely measure the nitrate content in your tank water without interference from amines- an element that can sometimes cause false readings. For freshwater or saltwater aquariums.

Internal Id



This test offers two ranges:
Low range: 0.2-10 mg/L (ppm) as nitrate
Medium range: 2-100 mg/L (ppm) as nitrate

Procedure for both ranges:
1. Fill test vial with 1 ml of water.
2. Add to this 4 drops of NO3-1.
3. Add 1 level scoop of NO3-2 powder (compress this powder against the inner side of the powder container). Swirl gently (do not shake) for 30 seconds. Let it stand for 3 minutes.
4. Color comparison:

Medium range:
Place the test vial on the white part of the color chart and compare colors looking from the TOP. Use diffuse daylight when comparing colors. If the color corresponds to a value lower than 10 mg/L nitrate then it might be better to compare colors as show fro the low range.

Low range:
If the medium range color comparion procedure gave a reading lower than 10 mg/L then you can use the low range procedure. This will increase the accuracy.

The color for the low range procedure has to be compared by looking through the side of the test vial. The white part of the color chart has to be held firmly against the opposite side of the test vial. Use diffuse daylight when comparing colors.

The color is, by looking through the side, amplified by approximately 10 fold. For this reason, you have to divide the color chart values by 10. For example, 1 will be come 0.2 and 50 will become 5.

Salifert Nitrate Teat Kit


Very accurate test.

Bargain and Important


I like Saliferts kits. They dont cost much and most importantly I find them to work well. I use this nitrate test kit once a week to keep an eye on my 150 gallon reef tank. It's important if you want to protect your corals. Good product and a good value.
