Kas on kellelgi kogemusi AZOO NO3 testiga? Ma ei saa täpselt pihta värvikaardile, kuidas seal vaatama peab. Mul mingisugune ettekujutus on, aga igaks juhuks kontrolliks üle. Ennast ei saa ikka alati usaldada.

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 5 ml of testing water with 5 ml of pure water. After
shaking, leave 5 ml 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, please dilute 5 ml of testing water with 15 ml 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 the color
chart : 0, 20, 40, 80, 160 mg/l.
4. If the tested value exceeds 160 mg/l, please dilute 2 ml of testing water with 18 ml of pure water.
After shaking, leave 5ml 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 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: 0-400mg / l

Et mis siin arusaamatut on? Tulemust tuleb võrrelda värvikaardiga ning alustada skaala lahjema otsaga (0,5,10,20,40 jne.), karmimaid näite mageveeakvaariumis vaja ei lähegi. Kuna reaalselt NO3 üle 5 ppm (mg/l) on vähemalt mageveeakvaariumis paljuvõitu siis on ilmne et test on niru - taimekasvuks on paras justnimelt 5 ppm; 10 ppm on juba palju ning 0 on loomulikult liiga vähe. Seega on kogu skaalas vaid üks OK näit, 2 piirnäitu ja lademes selliseid näitusid millega pole muhvigi peale hakata. Hea oleks omada ka 0 ja 5 vahepeal näitusid.

tänud. ma vaatasin ikka asjast nats mööda. nüüd mu mõõtmised näitavad, et NO3 on 10 või natuke üle ehk siis liiga kõrge.
