I love these. They work fast, give you a clear indication of toxicity levels and are easy to read.

I really don’t know what to say about a test trip and test for pneumonia. It works it identifies if your water has too much ammonia that’s all I can save for it. That’s all it does.

These strips are easy to use and understand. I love how nany come in one container.

I'm not sure about these. Many say that test strips are inaccurate. And when I used them the water drips from one to the other and caused the colors to bled into each other. So now I am unsure about them!

The only issue I had was super low ph in my in my tank. It will only read as low as 6.2. After multiple adjustments I realized that it was much lower than I thought. I lost some fish but it wasn't because of this product just my ignorance.

Somehow, my recent review of a bad product/merchant got put on my last review of this. There was no way edit it or remove it (although there were 'remove' buttons on all the OTHER product reviews. I contacted Amazon, but got no help. THIS is a WONDERFUL product and I will keep purchasing it!

Matches the others I bout from my local pet store, so good enough.

I have compared API drop tests to these strips probably a dozen times now. The 9 in 1 strips are sort of ok. The gh and kh are the most accurate, but there is not enough color scale variation so it can appear to be off by one or two points.The color of all the test areas can vary a lot between strips even testing the same water.The ph is very, very inaccurate and you cannot trust it at all. It's basically useless.The nitrite and nitrate are decent, and good enough to use for a quick check of those parameters.I do not have any iron or copper in my water so I cannot review how accurate these tests are. I also didn't test for chlorine or total alkalinity to compare and contrast.The really big issues with these tests, besides the ph being very inaccurate, is that the ammonia strips seem to be either incorrectly manufactured or just completely useless.As you can see in the picture, they do not change color completely throughout the test area; there are only a few tiny splotches here and there that change color if they do at all. I am cycling a few new tanks that I added liquid ammonia to in order to do a fishless cycle, so I know exactly how much I added in addition to also testing multiple times over multiple days with both API drop tests and these ammonia strips.And they do not work at all. Some strips will have a few blotches of color, but are still inaccurate. Some do not change any color at all from what their color is when new and dry from the package. The ammonia strips either had an error in manufacturing, are defective, or just never worked from the beginning.I also had a recent huge ammonia spike in one of my tanks (took too long doing maintenance on an external filter and the bacteria in the bio media died off too much is my guess,) and API test came out at the highest rate of 8 ppm. I tried a few of these ammonia strips and not a single one registered this, the most I had again were a few splotches of color and those colors did not at all come close to the actual high ammonia that was actually in the tank.I followed all directions, tried a few variations (taking out from water earlier, later, less swirling, more swirling, etc.) and saw no change in getting them to give any result or color change. The ammonia test strips are basically a useless rip off and do not work at all.So save your money and avoid these useless tests. I can only use them to get a quick idea of nitrite and nitrate but honestly wouldn't trust those either with how inaccurate and defective the other tests are.
