These are so much easier to read than the strips. I’m colorblind and have a tough time Distinguishing the shades on a strip. Just hold this with good light to your back and you can tell right off where your levels are. I also validated the result against my local fish shop. Glad I finally found these, will be buying them from now on

This has been a product part of an indispensable set of testing equipment advised by the aquarium community at large. This compliments the rest of the API freshwater testing kit liquid tests. It's not perfect in a sense. Some of my personal complaints are how the colors for different levels aren't quite discernible, and the amount of shaking required. These are nitpicking. The important thing is the test is typically pretty accurate in my experience.

this is my 2nd nitrate test kit from API that has gone bad in 3 months! But you don't know it's bad until you have someone else like your LFS test your water and find out your chemicals are bad! I have it in a temperature-controlled / room temp environment, so I have no idea why it would do that.

Not as convenient as salifert but the result is comparable if you follow the manual - shake bottle 2 really well. A budget alternative for nitrates higher than 10.

I have been using API test kits for years and normally would give it 5 stars. This new one has a plastic vial with a built in cap instead of the glass vial. Test results seemed off since I measure nitrates every week before a water change so I weighed it on my kitchen scale. Filled to the line it was 8ml not 5 (the glass vial was spot on) and the ppm was lower by at least 10 from the glass measure! Also hard to see the line on the new one. Thankfully I have plenty of the glass ones to use instead.
