API Nitrite Aquarium Water Quality Test Kit, 150 Gram, 1 Piece

Very simple to use. I like API test kits more than others as I feel its value for money - more tests per box and quite accurate.

Packaging is poor. Test vials will broke in this kind of package. New product. Expiry on 2021.

Excellent

Good but price is high as compare to market

Everyone should have Amonia and Nitrite test kit to test their water. its really easy to use.

This product help my aquaculture farming.

It's a standard product so no issues. Already using Ammonia API kit. Very reliable and accurate results.

The package came with the test tube Broken. There were No glass pieces inside - hence it is obvious that a broken test tube was packed

Good to have this to check, but all good

the test using these strips matched the aquarium test results from the fancy fish store, setting my mind at ease about acquiring shrimp as pets.

Producto indispensable para monitoreo de la salud de las bacterias que eliminan el amoniaco del agua salada de mis medusas.

This API Nitrite test kit is for testing fresh water or salt water for levels of nitrite. Used mainly for aquariums as nitrite, if present in water, can be harmful to fish. The test kit is very easy to use. You just fill up the test tube that is provided, to 5ml. There is a marking on the test tube so you know when it has reached 5ml. You then add 5 drops of the solution provided, put the lid on the tube, then shake it for 5 seconds. Wait for 5 minutes, then compare the colour of the water to the colours on the test card. It is that simple. Depending on the colour, the instructions can give you some advice on what to do, which is very helpful. They go into decent detail to explain some things, the headings are.... 1 - Why test for nitrite? 2 - Testing tips 3 - Directions (step by step guide on how to test water using the kit) 4 - What the test results mean 5 - Reducing aquarium nitrite levels 6 - Reducing pond nitrite levels These are written in English, then translated into French, Spanish, Italian, Portuguese, German, Dutch and Swedish. The test kit includes 1 - Nitrite test solution (with childproof safety cap) 2 - Test tube with lid 3 - Instructions 4 - Nitrite colour card The test can be done up to 180 times with the solution provided. The colour card has six different colours. The ranges are 0 ppm, 0,25 ppm, 0.50 ppm, 1.0 ppm, 2.0 ppm and 5.0 ppm. You can see the colour card in the picture that I added above. It also has a step by step picture guide on how to test your water. I mainly purchased this for when I was cycling my fish tank. Once the ammonia started to go down, the nitrite level was rising. I had to keep an eye on this level so I knew when to do water changes so my fish didn't become too sick. My fish tank successfully cycled, but it is also useful to check water levels after cycling. I normally test for nitrite 2 days after the weekly water change when all levels are settled. I believe that test results can be distorted if you test too soon after a water change because of the reaction in the water when you add dechlorinator. My nitrite has stayed at 0ppm but it puts my mind at rest to know for sure. All in all, this test kit has been very helpful to me, especially during the stages when I was just beginning my fish hobby.

Initial review: After following the instructions very specifically, I was unable to get a reading of copper after I dosed Cupramine into my 10 gallon quarantine saltwater tank. However, after letting the test tube sit for a day, I was able to get a copper reading. Read below for the full review and results: EDIT: After letting the test tube sit for an entire day, I can actually distinguish a copper reading that seems to be nearly accurate with the amount of Cupramine I dosed. I tested ANOTHER sample of the same water, and got copper color immediately? Both tests look identical and it is actually reading right about 0.5mg/L. I am not sure if I should trust the readings, although they would be spot on with the amount of Cupramine I dosed. I'll test it with a Seachem test kit tommorow and update this review. Also make sure to follow the directions precisely, you need to remove the cap and look down the test tube with the white background of the color under the tube, but don't let the tube sit directly on top of the card, the color will appear much darker. Hold the test tube above the card an inch or two. EDIT #2 02/19/18: The Seachem Copper Test kit arrived and the results are in: 0.5mg/L. Right at the amount I dosed. Tested again today with also the API Copper Test kit. Results again, are the exact same. 0.5mg/L. This means (in my case) both the API Copper Test Kit and the Seachem Test Kit are both precise measuring tools if you are dosing Cupramine.
