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

Purchased it yesterday and checked water in my fish tank. It showed 1.0. I added ammonia reducer and tested again next day and it showed 0.25. Looks like it works! The only thing I didnt like that it has two bottles and tube is too thin and you should find really flat surface for it when you change bottles.

I worked in three pet shops as a teen and later managed the slat water department in a very large pet shop in Philadelphia. I have kept fish since I was five years old but have been on hiatus for the past 20 years and not had any tanks. These kits have been around for ages and are very accurate if you use them for their true intended purpose; freshwater community tanks or similar. Dont try and use these the nitrite or ammonia for saltwater tanks of any sort. Dont use the pH test kit for tanks that need exact pH values for high pH animals like cichlids (though this is less of a problem if you read below). These tests are extremely economical and provide many more tests per dollar than any other kits available. My son is six and my daughter is four. We decided to raise tadpoles twice this year and needed to monitor ammonia, nitrite, and pH. The 40-ish year old design of these kits still fit that bill perfectly and were exactly what we needed. I wish the scale on the pH kit went higher, but it goes high enough for community fish. Tadpoles here tend to like higher pH values of ~8.2 and the pH kit doesnt go that high. However, I got a rough enough estimate if the pH test indicated that the pH was off the chart high as water isnt going to go much above 8.2 unless you use chemical inappropriately. Ammonia and nitrite test kits worked perfectly as in the past and averted many potential tadpole disasters and crying children. Weve kept snails, clams, some minnows, and loads of plants in the tank while the tadpoles have developed so the bio load was always changing. Still great kits even after 40 years at a very affordable price. Highly recommended for their intended usage scenario.

Does exactly what I needed it to do!

Ive used this for years and love it. I stupidly ordered this by accident INSTEAD of the nitrate test kit because I cant tell the difference between a letter change, I guess (to be fair, theyre obnoxiously similar sounding terms even though AMMONIA is ALSO a form of nitrogen and yet IT doesnt have the pre-fix nitro- in the beginning of ITS name; wtf, chemistry?!)

The description on the Amazon site claims this product measures nitrate. IT DOES NOT!!! This is a misprint by an idiot. Nitrite is deadly; nitrate is added to bacon.

;)

I just bought this as a replacement for my nitrite bottle in the master test kit - Id run out. Awesome that it comes with another test tube.

very good. Arrived leaking into the box.

Works as expected.

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