API AMMONIA 130-Test Freshwater and Saltwater Aquarium Water Test Kit

works fine

The api water testing kits are pretty much the gold standard for checking the water parameters of aquariums.This one just tests for ammonia, and is incredibly accurate. Easy to use, as well. Only takes 5 minutes and you can read your ammonia level by the color of the water in the test tube.It is tempting to try to save money and use test strips, and I did so, even when told by other aquarium enthusiasts that the strips aren’t accurate. I had what I thought was a newly cycled tank, using test strips and kept getting zero ammonia, so added my betta fish. Soon the fish was acting weird, like something was bothering him. So I got this test kit, and the ammonia was very high! And the test strip at the exact same time still read zero.So please do yourself a favor and go for the test tube rather than than the test strips!

I always use API they are great!

I am a ponder - have been for years, and frankly, the ammonia test is the one I use most. I bought a cheaper test kit, and found it to be utterly lacking in sensitivity and display. This is the one you want. Easy to use, easy to read and understand. Far better accuracy. Some tests are just too vague.

This test is essential for new aquariums. Unlike the test strips, this is more accurate and economical. I was burning through test strips like nobody's business. It comes in 2 bottles and I took one star off because I received a bottle with a broken safety ring. Now, it's difficult to open and close the first bottle. The second bottle is fine though. Both bottles are needed for the test. The colors on the card that's used to compare the results are easy to read. It provides a wide color gradient from yellow to dark green, which is a plus with aquarium water tests. Anyone who has tested nitrates would understand that it can be difficult to compare similar shades of orange. Since this test for both ammonia (NH3) and ammonium (NH4+); you would have to go online and find an ammonia calculator to find the actual amount of NH3 because it is dependent upon mostly pH and temperature. The amount of NH3 should not be more than 0.02 ppm, the lower the better. It would be nice if API provided an ammonia chart.

Hi since 1996 this was my first ammonia test kit and still being used today 2026 to monitor the Nitrogen cycle and if something questionable is happening in the aquarium.Yes there are more expensive electronic testing devices. Have compared them. API is still accurate and affordable

I'm using with the Ammonia Test Kit together with this. I did a deep research and found out this is better than the strip one.pros: Very accurate and easy to use.cons: I wish they make the "pH Down" solution bigger than "pH up" because usually we want the water to have lower pH level (depends on the fish type but, generally).

I worked in three pet shops as a teen and later managed the salt 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. Don't try and use the nitrite or ammonia for saltwater tanks of any sort (even though the kits say the can do salt water, they don’t do it well). Don't 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 doesn't 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 isn't going to go much above 8.2 unless you use chemicals inappropriately to alter ph.Ammonia and nitrite test kits worked perfectly as in the past and averted many potential tadpole disasters and crying children. We've 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.

This is a good product to use when you are new to the hobby. Product is little costly but may be worth the price.

good product to monitor the ammonia in your tank .

As described.

API test kits are very reliable. This is a great buy for when you need to restock the master test kit, I like that it includes a test tube.

Works well, precise readings and brilliant for keeping check on my aquarium amonia levels. Easy to use, and the card makes it easy to check the results. Used lots of times and will definitely buy again when needed
