Review: As easy as it gets... - 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.
