Interesting.
Well, I feel a Hanna checker is the most accurate way to check water parameters.Sometimes they can be finicky.Also getting the powder out of the package can also be challenging.I suppose the only negative is that there're pretty expensive.

Accurate but with a few steps
I get why most people are apprehensive about using this nitrate checker. When you open the box it looks intimidating. There’s a lot of steps you must do to get a reading. But I’m telling you, it’s worth all those extra steps. It becomes muscle memory after awhile. If you’re nitrates levels are over 5ppm, there’s a method of checking that as well when you dilute it but you’ll need freshly made saltwater. I tested this against other nitrate tests and it’s spot on.

Way, wayyyyyyyy too complicated and time consuming.
Mind blowingly overly complex procedure !!!!So many difficult steps. Dont waste your money , unless you're extremely smart and have lots of time on your hands. ( This type of product can't be returned . )Wasted 65.00

Works like a dream
This provides a straight forward way to confirm nitrate levels. My reef tank tested at 0.01 ppm, which is what I was expecting.The test is a three step-process that requires a bit more effort than for some other parameters like alkalinity or calcium, but doing what is required is easy enough. So long as you follow the instructions this is not hard to use.

seems to work
Honestly I used it once . I do weekly and sometimes by weekly water change with a high quality salt .I checked my nitrates once going through the cycle 6 months ago on a new tank . Been in the hobby 30 yearsThe only thing I check is salinity during water changes . for a beginner this meter can be very useful .

Completely satisfied
Easy to use and very accurate. The case it is kept in is awesome as well.

Needlessly complex
I am sure that this is extremely accurate as most Hanna products are, but frankly it is needlessly complex and has more steps than driving a car. Unless you really need the sub 5ppm accuracy (most dont) go with a simpler kit. The rest of the Hanna Checkers I have I wouldn’t trade for the world. I share some of the blame for the not researching this more.
