Review: Easy to do and read results! Appears accurate. - I ordered this because I wanted a back up for my API kit when I was getting readings off the scale (and hoped it was the kit, and not my water. Nope. Water. Major water changes and it got on the scale. Work in progress.) So, this kit gave a similar result as the API, but so much quicker and easier! Only 2 steps, easy swirling for 30 seconds, instead of shaking vial with a leaky cap getting chemicals all over your hand like the API does. the flat bottom set on the card makes reading the color much more definitive than the round tube and guessing at the distance and light direction. Yes, there is a good bit of interpolation in the high range where I am currently around 70, but the obvious color intensity and tone is much better than others. The difference between 60 and 80 is not really a critical bit of info, as those are both "too high". The ranges get closer together in the lower ranges where target levels are more specific. Laminating the color card would be my one suggestion. I am sure I will douse it with salt water soon. (Unfortunately, before ordering this Salifert kit, I paid a fortune for a Hagen kit at my LFS. It is useless. The color of the resulting solution for the Hagen is a bright magenta, matching nothing on their scale of rosy pink on the flimsy paper booklet. I noted that the color of that solution was in the tone of the Salifert scale. I poured approximately 1 ml into the salifert vial and compared to the chart, and got a very similar result! Conclusion: the Hagen vial shape and paper chart are inferior, although the chemistry may be consistent and accurate. It is impossible to read.)

Well after using both side by side for a few months I definitely think there are pros and cons to both brands, and I have learned to just deal with the cons and you will have to as well. My takeaway from this product is that the test is quicker and easier to do, easier to read results, but i’m not confident that it is any more accurate than API. In my experience, there is more room for human error with this kit - particularly with the spoon and powder. Both brands can show you when your nitrates are too high: red for API and bright pink for Salifert. And that’s all you really need to know. If API figured out their color card printer, I would always choose that brand over this one. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/5898511-salifert-nitrate-no3-test-kit](https://www.desertcart.pt/products/5898511-salifert-nitrate-no3-test-kit) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-08-24*
