## Customer Reviews

### ⭐⭐⭐⭐⭐ No regrets!
*by A***S on May 19, 2025*

Easy to follow instructions. Tests are accurate. Great value considering inaccurate tests kill livestock.

### ⭐⭐⭐⭐⭐ Great product
*by R***G on September 8, 2025*

Exactly as it says. Super useful to have on hand for any salt water aquarium home.

### ⭐⭐⭐⭐ Easier to read than API and seems fairly reliable
*by D***K on April 18, 2014*

I get consistent readings with this kit and it is easier to read than API's color charts. It has sample jars instead of vials, so you are less likely to knock them over when performing the tests. The individual tests use a reference sample and color wheel (test jar goes in the center over a pure white background, reference jar has the same volume of water and the colored circles that correspond to different concentrations are rotated under the jar and the two are compared), with this kit you place the jar over one of two blank circles and compare to the colors around it to determine the concentrations. Some can be difficult, but moving the jar back and fourth between the two circles helps in determining which color is closer. There is far more color difference than with the API kits. With any colorimetric test, make sure you are in good lighting. I was originally checking under one brand of 6,500K CFL bulb and my tank kept registering ammonia. I tested freshly made salt water and I was getting the same results (using RO water, which was testing 0 on everything, including TDS). Checked the sample under a different 6,500K bulb and read 0.
