## Description

Keep your fish healthy and thriving by testing your aquarium water's NO2 levels regularly with this easy-to-use API NITRITE TEST KIT for freshwater and saltwater aquariums. Testing water parameters weekly helps prevent invisible water problems that can be harmful to fish. Nitrite is produced in the aquarium by fish waste and uneaten fish food. Low levels of nitrite inhibit respiration and suppress the immune system; high levels cause suffocation. The API NITRITE TEST KIT tests for harmful nitrite levels from 0 to 5 ppm. This product comes with one nitrite bottle, one capped test tube, one instruction manual and one color card. API NITRITE TEST KIT can be used in freshwater and saltwater aquariums. With API aquarium products, it’s easy to keep a beautiful saltwater, freshwater or reef aquarium. For almost 60 years API has developed premium solutions with proven and effective results for your family and ours. API offers a range of testing kits, water conditioners, and nutritionally superior food, because we’re dedicated to making a better underwater world. They work to provide a safe, hospitable environment for fish such as tropical community fish, cichlids, goldfish and more. At API, we understand the rewards and relaxation of fishkeeping because we have a passion for fish too.

Review: Works perfectly fine! - This test works perfectly fine. If people say it doesn't work then they're doing it wrong, just be sure to follow the instructions. It's pretty quick to use and last for quite some time so it's totally worth it, plus the test strips are not very accurate.
Review: Good product, will buy again as needed. - This product works very accurately. Nice to be able to buy this separately and not purchase the whole kit. More expensive then the strips but I trust this process.

This test works perfectly fine. If people say it doesn't work then they're doing it wrong, just be sure to follow the instructions. It's pretty quick to use and last for quite some time so it's totally worth it, plus the test strips are not very accurate.

### ⭐⭐⭐⭐⭐ Good product, will buy again as needed.

This product works very accurately. Nice to be able to buy this separately and not purchase the whole kit. More expensive then the strips but I trust this process.

### ⭐⭐⭐⭐⭐ Great Test Kit for the price, it gives you a pretty good estimate of your Nitrates when they are high.
*by R***G on March 26, 2016*

API kits are fairly accurate for the price, I highly recommend them for salt water aquarium owners that need and should have at least 2 kits of every important test type so they can cross reference results if they feel something is wrong with a particular test result. API fills that niche perfectly with pretty accurate easy to use kits that cost a quarter the price of the more accurate ones like Salifert, ELOS and Red Sea Pro. The API Nitrate Kit is as simple as it gets, just fill the vial to the marker or better yet use a syringe and add 5ml as directed. Then add 10 drops of reagent "A". swirl for a bit then shake reagent "B" for 30 seconds very vigorously and add 10 drops of that. Shake the whole thing for one minute vigorously and then wait 5 minutes to get a result. IMPORTANT NOTE: If you forget to shake reagent "B" you might as well throw the whole bottle of reagent out. This solution separates out in the container after a few hours into layers of different chemicals. If you don't shake it, you will be dripping out 10 drops of just one of those chemicals and remaining mixture will be compromised. The end result is that the next time you use it and shake it up properly the typically result is a lower reading than normal. Just remember to always shake reagent B properly for 30 seconds and you wont have any problems. If your Nitrates go down to reading Zero on the API kit, then it's time to move to a more accurate kit that is designed to read very low Nitrate levels. If your keeping a SPS Reef Tank you need the Nitrates to be near Zero and the API kit will not be accurate enough to read the small amounts that may be in your aquarium. For FOWLR Tanks, Nitrate is not as not as big of an issue, so an API kit or two is all you will probably need.
