nitrite test1. Fill sample pipette to base of bulb and dispense to a test cavity of the test plate. Repeat, adding to same cavity.2. Add one drop of Nitrite Reagent 1. 3. Compare to color chart (top scale) after 3–5 minutes.4. Promptly dispose of completed test solutions by rinsing test cavity under running water.
nitrate test1. If you have just run a nitrite test, you can jump to Step 3, otherwise, ﬁll sample pipette to base of bulb and dispense to a test cavity of the test plate. Repeat, adding to same cavity.2. Add one drop of Nitrite Reagent 1. 3. Add one level scoop of Nitrate Reagent 2. Stir to mix. It is normal for not all powder to dissolve.4. Compare to color chart (bottom scale) after 5-8 minutes.5. Promptly dispose of completed test solutions by rinsing test cavity under running water.
Reference testThe proper performance of this kit may be validated by running a nitrate test in the normal manner except that the reference sample is used in place of aquarium sample. It is not necessary to run a reference test to use this kit. The only time you might choose to run a reference test is if you have cause to believe the test is giving incorrect results. If you run a test using the reference sample and obtain the correct result (based on the known reference value provided) then you know the test is giving correct results. To run a reference test use the Nitrate Reference as the sample in a nitrate test. Reference value is 10 mg/L.
HintsIf the test plate becomes stained, soak or clean with a dilute bleach cleaner, then rinse well. It may be difﬁcult to thoroughly clean Nitrate Reagent 2 from the test plate. This could cause some nitrates to be misread as nitrites. For that reason, you may wish to reserve some cavities of your test plate for nitrite use only, i.e., never use Nitrate Reagent 2 in those cavities. If necessary, Nitrate Reagent 2 may be purged by soaking test plate in vinegar overnight. If color response is off scale, run test on sample diluted with distilled water. Dilution may be prepared directly in test cavity: for example, use 14 drops of sample with 14 drops of distilled water, multiply result by 2; use 4 drops of sample with 24 drops of distilled water, multiply results by 7, etc. If you have any nitrites present, note the corresponding nitrate value for that color, then subtract that from the ﬁnal nitrate value you obtain.
InterpretationThis kit may be used with freshwater or marine water. The values reported by this kit are expressed as nitrite (NO2—) and nitrate (NO3—), not nitrogen. To convert to nitrogen divide by 3.3 and 4.4, respectively. Nitrite is toxic and should be undetectable in any well established aquarium. During cycling, it may exceed 20 mg/L. Nitrate is relatively non-toxic, but it is advantageous to control it to under 20 mg/L.

Aquarium use only! Keep away from children.
