API NITRITE TEST KIT 180-Test Freshwater and Saltwater Aquarium Test Kit

Works well to test nitrite, however Id recommend just getting the master test kit for the price of the two. Youre better off getting more tests than just this one. This test has been accurate and helped me lower my nitrites though.

Good kit

Great for testing my aquarium.

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.

Great, product was exactly what I expected.

Excellent price for a great product!

Really easy to use. I personally do not have trouble differentiating the color readings. An absolute must for anyone that’s serious about fish keeping. However, if you’re getting this, then I assume you’re getting the Ammonia and Nitrate (which is hard to find on Amazon - got mine from Petco) kits as well. If that’s the case, and it should be, I’d just shell out the few extra $$ and get the API Master Test Kit instead of the Ammonia, Nitrite, and Nitrate all separately.

Well it works. What else can I say?

I have bought and used may API test kits over the years and they are usually a reliable product. But this one has me baffled. Is it a return or just a quality control issue. First off, upon receiving it, I took out the instructions to read them. HUM???? Instructions are for a NITRATE test kit, not NITRITE test kit. Ok, simple instructions are on the back of the color card. so, I start the test and add water & drops to the test tube, snap on the cap and turn it upside down as instructions. The water/fluid leaks out! I press on the cap hard but it still leaks. BUMMER!!!!!! None of my other test tube and caps leak. Come on API, get your act together. Is this a QC issue or do you sell seconds on Amazon????

It works.
