API Nitrate Test Kit

Does what it says. I wish the color gradient was a bit easier to distinguish but that's a minor nit.

Important information:

I was instructed by the Local Fish Store and people in my aquatic club to shake the 2nd bottle for more than 20 seconds closer to 1-2 minutes before using. If you don't shake it well enough, it will not provide an accurate level of your NO3 levels. I did a test and there was a difference Per instructions it displayed an incorrectly low NO3 level, shaking it longer gave a higher NO3 level.

I have used API tests for years and have always had reliable test results. (tested against other brands) the color is hard to read on the high end of this test as the color differences are minimal but keeping up with your tank it is not an issue.

I wish that the time it takes to do this test was condensed (drops in from bottle #1 shake tube. shake bottle #2 30 seconds. drops in from #2. cap tube shake for 1 minute, let sit 5 minutes ... read results. but all in all like API and their water tests.

Had another kit that did not work at all. This one works great! Don't be confused by the picture though, this is only the Nitrate test the only one I needed. If you're looking for ammonia and nitrite too, you might want to just buy a kit.

I've always used the test tubes over the dip strips when it comes to testing my aquarium water, simply because they take MUCH longer to run out (which is a big deal when you're testing four aquariums). Also, a lot of authors of many of the aquarium books and magazine articles I've read consider them more accurate the other conventional forms of water testing (though I find that the test strips really aren't all THAT far off and the difference is neglegible). I origninally purchased the product as a kit with all the other stuff over two years ago before I FINALY ran out so it lasts a long time. I would definately recommend this product.

I've had my saltwater tank for years and know how to test for nitrates. This test is simply NOT ACCURATE! I have to take my water to the LFS to have it checked for now while I shop around for a better kit, as the one I have been using is no longer around....Don't waste your time.
