My nitrate test shows brown, and has ever since the first test strip I've used. Brown isn't a color on the color chart. What does this mean for nitrates?
Answer by ChewyNov 06, 2018
The brown color refers to the hardness of the water. Please see below for a reference.

How do you know if test strips are good or not is alkalinity supposed to be yellow before test

These test strips indication spots will have a faded color. Once the strip is dipped in water, the color will bold showing the water levels.

Love the ease of using these strips

I've had these in use for several years and with my established tanks, they are not far off from when I used the solutions to test.

Defective product

Defective, I ordered these in January but I didn’t open them until today as my other bottle just ran out today and noticed half of them looked damaged, especially the nitrate top pad and pH bottom test pads on them. I tried the damaged ones and they don’t even work. I always get these in the past but this batch was no good, so basically trash. I will not be ordering these again These were expensive for me and I usually just use them to test the nitrates and ph , but basically useless because they look damaged and don’t work.

Good indicator and quick

Liquid tests work better but these are quick and easy and include GH and KH. They are handy though.

Aquarium test strips

I love these & also much better of a price on here compared to what I was paying in the store. I got 4x as many for $4 more. $12- 25 in store or $16- 100 chewy. 5 star price!

Ease of use is the goal

If you want great accuracy then don't buy these and spend some money on a more expensive (API Mater Test Kit) or get an electronic water tester (multiparameter device if you want to drop some serious cash). Otherwise, this is great for its intended purpose of giving you an idea of where your water parameters are real quick.

Not very accurate

This has nothing to do with Chewy because I love ordering from them. This is to do with the product. I have been keeping fish for a long time now and these are the very first test strips that I have ever tried. I'm actually shocked that so many have rated this product so highly. One of the most important parameters you check in your aquarium is Nitrate. And I would say it's the most inaccurate part on the entire test strip. The KH & PH is hard to read honestly. Checking this against the API kit my nitrates where at about 40 but on the strip it was off the chart. And the only reason my Nitrates where that high was because I was treating my tank for ick. Usually my Nitrates sit at about 5 ppm with a denitrator.

Super easy

These make it very easy to monitor the water conditions without buying and getting out a bunch of test kits. They seem to be fairly accurate as well
