Nitrite 0-25 ppm, Nitrate 0-500 ppm Two Pad Test Strip [Vial of 50 Strips]

These test strips are great they give me a idea of the range. It took some getting use to because it goes off of color and the range can vary. But compared to my other tests its in the same range. But I can complain its a lot faster then pulling a kit out. I can easily dip and know if my level are going down quickly. I still used the hanna checker to get a better idea of the number but this is great for quick tests to make decisions. Very easy to use. The tests last a while and are cheaper then buying reagant refills for my testers. You should still be testing with other tests to get a better idea of the number but this is a huge time saver. and no mess or cleaning.

Extremely fast and easy to use. The only down side is that it's a bit pricey for what you're getting. But if you live in the US Midwest, you probably want to pick some of these up...

We wanted to check our water quality and this item did the job, making us feel secure in knowing more about the quality of our water.

Producto ok y a tiempo

I made two kinds of water to test this litmus paper, but it didn't seem to have a strong reaction. It may be useful for checking the safety of regular drinking water.

I love knowing what my levels are. And these seem to be spot on

Did it's job

I was looking for an easier way to test my nitrate levels in my aquarium rather than using water samples and drops. However, these have such a large nitrate range (0-500), that the increments of results are rather unhelpful. Furthermore, the color differences are VERY close. It's easy to tell if you're in the 0-100 range or 300-400 range, but really hard to tell if you are at 25, 50, or 75. The colors appear almost exactly the same.Pros:-Seems accurate.-Easy to use the test itself.Cons:-Very hard to read, as the colors are all shades of light pink.Perhaps for research applications this could be useful, but not particularly useful for aquariums if that's what you are after.
