NO3 Test

AZOO NO₃ Test
For freshwater, aquatic plant, saltwater, reef aquariums and ponds

Nitrate is the final product when bacteria decompose protein.
It is also the product when nitrifying bacteria oxidate NH₃, NO₂.
The resource of NO₃ is from fishes' excreta, residual baits, and dead fishes.
NO₃ is also the nutrient resource of algae.  When NO₃ level is too high,
it will result in heavy algae growing.  Meanwhile, it will influence the fishes
health when live in high NO₃ surroundings.  It also will restrain water plant's
uptaking of Ca, Mg, and Fe, and cause the malnutrition of water plants.
Therefore, NO₃ value should be maintained below 5 mg/l in water plant aquariums.

ANALYSIS:
1. Obtain the reading value of the test result by comparing with the calibration
    on the first line of the color chart 0, 5, 10, 20, 40 mg/l.
2. If the tested value exceeds 40 mg/l, please dilute 5ml of testing water with
    5ml of pure water.  After shaking, leave 5 mal of the water in the sample vial,
    then repeat the same testing procedure.  Obtain the reading value resulting from
    this repeated test by comparing with the second line on the color chart:
    0, 10, 20, 40, 80 mg/l.
3. If the tested value exceeds 80 mg/l, ;lease dilute 5ml of testing water
    with 15ml of pure water.  After shaking, leave 5ml of the water in the sample vial,
    then repeat the same testing procedure.  Obtainthe reading value resulting from
    this repeated test by comparing with the third line on ehe color chart:
    0, 20, 40, 80, 160 mg/l.
4. If the tested value exceeds 160 mg/l, please dilute 2ml of testing water
    with 18ml of pure water.  After shaking, leave 5ml of the water in the sample vial,
    then repeat the same testing procedure.  Obain the reading value resulting from
    this repeated test by comparing with the fourth line on the color chart:
    0, 50, 100, 200, 400 mg/l.  Hence, the maximum testable level can reach 400 mg/l.
5. If the tested value exceeds 400 mg/l, please have a partial water change to
    improve the water quality.  NO₃ had better be maintained below 5 mg/l in water
    plant aquariums.

RANGE:
0~400 mg/l
