    If youre like me and youre always starting up new tanks this is a must have item. I like to do fishless cycles and its important to test for amm and nitrite which are extremely toxic to fish. This item is easy to use just add 5mls of tank water 5 drops shake and wait 5 mins the color chart is easy to follow and accurate. I can only find this test kit online and the price is always great with fast shipping.

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

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.
