Nitrites

The nitrite test comes from the Saltwater Master Test Kit created by API MARINE

What the test is used for:

 This test is used to test the concentration of nitrites in the aquarium in the unit of part per million.

Effect of Nitrites on Aquarium:

 Nitrites are a product of ammonia after it has been converted by nitrosomona bacteria into the nitrites.
 Nitrites are toxic to the life in the tank and the concentration should be kept as low as possible.

Test Procedure:

 1) Fill test tube with 5 ml of aquarium water
 2) Add 5 drops of Nitrite Test Solution
 3) Cap the test tube and shake for 5 seconds
 4) Wait 5 minutes for the color to develop
 5) Compare the color of the solution to the Nitrite

Recommended Nitrite levels (ppm):

 Optimally, the nitrite level should be at 0ppm

Data:

 3/12/2019
 The test indicated a 0ppm concentration of nitrite
 *insert image of test*

 3/21/2019
 5.0ppm concentration 
 This indicates that our level has risen --> sea urchin addition to tank

 03/28/2019
 0ppm concentration

 04/04/2019
 0ppm concentration

 04/17/2019
 0.5ppm concentration
 After the sea urchins were introduced, the biological filter could not keep up, increasing the concentration of nitrites

 04/23/2019
 0ppm concentration
