    Distilled Water Reads 5; API is The Closest to ICP Analysis
  

*by A***R on Reviewed in the United States on May 10, 2020*

Where to begin at how jank of an excuse this ‘test’ kit is. The dropper bottle is the poorest quality I’ve ever seen to dispense a reagent. The bottle starts dripping with the smallest tilt. Upon trying to shake the bottle, reagent leaked from the seams and splashed everywhere. The 5mL syringe arrived cracked so is unusable. This kit also comes with 2-3x as much of the powder reagent as you’ll need. Honestly the quality and chemical accuracy of this kit is as if it was designed by a group of children doing their first science fair gig where they 3D printed the reagent bottles, caps and syringe expecting it to be completely accurate. Regarding the chemical accuracy of these tests, it’s consistently off by about 5ppm (reads lower than ICP has ever revealed when testing stock solutions in the 5-10 range). The only thing that makes this kit stand out is the color comparison chart which isn’t even that helpful considering how inaccurate the measuring equipment they provide is, always leading to different shades of color when retesting the same water Or stock solutions back to back. Overall a cheap and inaccurate product that uses the poorest quality equipment possible to provide a rebranded, and less accurate, nitrate test than API. API has a focus on chemical accuracy at least, and only requires you to shake a reagent bottle as an extra step when compared to this NYOS excuse of accuracy. It’s funny how all the positive reviews have no mention about the actual product capabilities or quality (dispenser bottle, measurement spoon, how the caps leak every time you remove it) but focus on how ‘easy’ it is to read their good test results when in reality these kits read 1-5 ppm lower. Must be a bit excited over lower nitrate readings. I’ll stick with more accurate measurements over the false confirmation bias of why I spent $25 to get useless measurements. Granted I only purchased this kit once, it was enough to  really showcase the money minded strategy of this company.

    Too much hassle, not enough product for the money.
  

*by W***O on Reviewed in the United States on January 25, 2021*

I found this test to be accurate and easy to read, but the materials themselves are difficult to manage. There are so many pieces and parts to this test that you absolutely cannot lose.The dropper bottle was really loose, in that even the slightest squeeze could mean multiple drops would come out too fast to count. This was pretty bad because there didn't feel like much liquid in the bottle to begin with. I ran out not long after purchase, and I definitely got a lot less use out of the kit than I do with API tests.If the kit cost less I'd buy again, but it's just too much hassle and not enough product for the money.

### ⭐⭐⭐⭐ 







  
  
    Good Saltwater Nitrate Test, but not Great.  Much Better than API test kits for nitrates.
  

*by M***N on Reviewed in the United States on August 23, 2015*

I like this kit, but I can't say I love it.  It is pretty accurate and not too difficult to use but I would like more resolution and I don't like the bottle that is used for adding drops of reagent.  The bottle seems like it is more than 1/2 empty and is not the best bottle I have seen.  It feels kind of cheap and fragile.  I would have preferred that you raise the price, get a better bottle  and then fill it.  I also have not really fell in love with adding the powder.  Its not bad but opening and closing the little glass vial makes me think I am going to slip and end up spreading it around the room.  The little vials for water are great.  They are the same as the powder, but for liquids they are not as bad since it is only water.  And I like the lids better than the test for the API test kits.  The color comparitor is beautifully printed and accurate, but I wish it was a little heavier and better waterproofed.  It is better than the API test, but I don't love it right now.  (I wish Hanna would make a colorimeter for saltwater nitrates)
