### ⭐⭐⭐⭐⭐ No regrets!

### ⭐⭐⭐⭐⭐ Red Sea convert. Bye API
*by J***I on April 2, 2015*

I really can't say enough good things about this test kit. I was formerly using the API Saltwater Master Test Kit. This is my first saltwater tank and I was new to the cycling process. The API test kits did not help in that regard. The results were always ambiguous and I could never tell with any certainty what my levels were. The instructions on the API kits are also not incredibly clear when it comes to how you are supposed to read the colors. Do I look through the tubes? Hold them towards the light? Place them in front of the card in an upright position? In front of the card laying on a table? Depending on how you hold the tube when you interpret the color you can get a variety of readings. I always thought my tank had detectable ammonia. It never seemed to go down. I was really starting to stress about this especially after I added in my first two fish. Then I decided to order the Red Sea Marine Care Test Kit. This kit is amazing. First, it comes with an extra test (KH) that the API test kit doesn't include so that is great. Reading these tests is also fool-proof. You place your vial in a white circle with the color values surrounding your sample. It is plain as day the angle at which you read your sample. I tested my tank with API and Red Sea when I first got this kit in the mail. API seemed to indicate that I had 0.5ppm ammonia, 0 nitrite, and 10ppm nitrate. Red Sea showed I had 0 ammonia, 0 nitrite, and between 2-5ppm nitrate. For me, that is a big difference and a huge relief. I had been doing small water changes daily but still thought I had ammonia based on the API kit. So now I am a convert to Red Sea. Their tests are more accurate because reading them is less ambiguous. The box this kit comes in is hard plastic like other Red Sea kits and I think it will hold up better in the long run compared to the cheap plastic and boxboard that API uses. I am also a former clinical laboratory scientist and the Red Sea kits seem like more thorough and accurate tests because of the multiple reagents they use and the additional time they take compared to the API kit. Tests that are read in just a few minutes and with the addition of a few drops of one liquid seem like they would be less precise. But that is just my opinion considering my background. I would need more data regarding specificity and level of detection etc. to support my claim.
