    I have three products of this line of testing. They are all very accurate in reading the levels in your fish tank. Awesome stuff!

    Provides Nitrite reading in 5 minutes. I use a 3 ml syringe and 3 drops to get almost twice as many tests out of the kit.

    Results are quick, testing is easy and reading the results is painless (with a light, otherwise the color of the water can be difficult to see)!

    The test kit works great. However, the vials leak water when you shake or even turn them over.

    i highly recommend this as a refill when you have used up the nitrite portion of the API master tes kit.

    This is a good kit. Lots of tests left in the kit after the initial cycling of the tank. I bought this separately because I still have some old Doc Wellfish (same company..old moniker) Ammonia, Nitrate, Ph, GH, and KH, kits...they still work and they are over 18 years old! Much better than strips. If youre starting from scratch...I would get the master kit.

    Not only helpful for keeping fish from mysteriously dying but easy and fun to use. Livebearers now days are not as strong as they used to be in all types of water conditions and good water quality is essential. This product will let you know when your nitrite is down near zero with easy to use color codes.

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 glass 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.
