API Test Kits Review

To monitor the Ammonia, Nitrite, and Nitrates in my pond I have used a couple of different kits. I have even used the test strips but found they were not informative enough to really know what was going on. I have found the API brand readily available and generally easy to use. It is only slightly more expensive to buy the kits individually than to buy a multiple tests kit. The multi test kits may have items you don’t need like pH test kits if you already have a pH meter. The individual kits seem to last longer too and you don’t have to worry about running out of one test before the others. One other thing I like about the API kits is that the color separation between various levels of Ammonia/Nitrogen are more distinct than other kits. There is less guess work between zero, and differing levels.

Ammonia test kit
Comes with test tube and two bottles of reagent. Merely fill the test tube to the line (5mm) and put 8 drops of each solution, then shake well. After 2-3 minutes the full color will develop and you can match it against the water proof color card for salt or fresh water. Dual use test kit for aquarium or pond. Color card is Yellow for zero, green for .25, the blues for higher levels.

Nitrite test kit
Comes with test tube and one bottle of reagent. Add water to line, add 5 drops of solution. Shake and wait. Match color of liquid to the colors on the included cards.


Nitrate test kit
Comes with test tube and two bottles of reagent. Add water to line, add 10 drops of each solution. Shake and wait. Match color of liquid to the colors on the included cards. Bottle #2 requires shaking/mixing well before adding and instructions indicate the two reagents should be vigorously mixed in the test tube.

The importance of using these products is that the pond owner can monitor the ammonia and nitrogen levels in the pond and help maintain healthy water for the fish. Kh/GH, phostphate, chlorine/Cloramine and other water tests are also available.
