I have several tanks and run tests on them regularly. I like my API products for my aquarium testing and filtration.

This is a two bottle test not a two plus powder that the Tetra kit is. It does take agitating and there can be some aggrevation as the cap on the test tube doesn't always prevent spattering, a finger over the cap on the tube plus wrap it loosely in some paper toweling to prevent showers helps. You do have to agitate one bottle for 30 seconds before adding the drops, there must be something to put into suspension that can settle out. Then you have to agitate the tube for a minute, again, must be to allow something to react that's suspended in that second bottle chemical. It also has a 10 min 'reaction time'.Test results are spot on comparing the Tetra (with two fluids and zinc powder) and simpler IMO to perform.

If you have an aquarium, you must have this, you have to monitor nitrates. I've been I the hobby many decades and API is a quality brand and I like the straight forward directions that are simplified on the back of the color chart and then more detail on the extended directions. You should also only use test kits that have an date code/ expiration date on the bottle.

I was hoping to recieve a fresh kit and did. Glad I did not give up on the api kits here. Last one nh3 nh4 kit was over a year old. Not sure if it really matters but I preffer fresh kits

It works just fine. You just better hope you are not color biind. I tested water from several different sources and they produced the results I was expecting.

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.

API makes some great water tests and some don,t work but Nitrate test is good so much more accurate (versus the strip kind) I use some of their tests for our aquariums and was familiar with this product when this was purchased, so no surprises here.

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.

API makes great water tests and these are so much more accurate (versus the strip kind) I use all their tests for our aquariums and was familar with their products when this was purchased, so no surprises here.

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.
