    Totally useless when cycling a tank when you have high nitrites, can’t tell a lick of difference

    What more is there to say? It tests aquariums for nitrite. Actually you do the testing and take a small water sample, add drops of reagent and match colors. If you find nitrite you need water changes. Pretty simple stuff.

    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.

    Test seems to work, showed varying levels as new tank was cycled. The small glass tube warped somehow when I didnt empty the solution. Either chemical reaction or from too much exposure to sunlight on window sill? I dont know but it crumbled into small shards. Pretty annoying.
