| Directions | In new aquariums, ammonia should be tested every other day until the ammonia level measures 0 parts per million (ppm) or mg/L. In established aquariums, ammonia should be tested weekly to make sure it is at a safe level. This kit contains 25 test strips and reads 0-6 ppm (mg/L) of ammonia in fresh and saltwater. Just dip and read to measure ammonia in one easy step. |

Accurate pH tester for fish water
Really happy I purchased these ... after learning via PetSmart that our tap water was super low pH due to a shallow well which apparently killed our betta fish after 7 days. I got these to test our water with conditioner (yes, I was too lazy to take another sample to the store and I'm pretty sure they use these same strips). I also wanted to test our bottled spring water, which is what I use for our new fish (no added conditioner on my part). I learned with these sticks that our tap water, with or without added conditioner, is very low pH and our jug of spring water is perfect. Our fish is still alive (and very active) so I'm thinking these testers are very accurate. I may never need 20 of these but for $6 I'm glad I have them ... if we move, get a saltwater tank etc. Overview-you take a strip, swirl it twice in the water, don't shake off and wait 30 seconds (I found waiting a bit longer was more accurate). The color is a little off if you look 5 minutes later so don't wait too long). Done. Easy and accurate.

Still work two years later, seem to be accurate
I started using these as a quick and easy test for the hospital tank I set up. It comes back 0 when it makes sense. It also tested higher values which made sense as well: 1) anemone looked like it was going to die in my display tank, I put it in my hospital tank before leaving for the weekend. Sadly it died. I tested the water when I got home and it was maxed out on the chart for ammonia (makes perfect sense for dead nem) 2) I had a firefish die in the QT tank - must have been overnight. For a much smaller fish, having died recently, it reading around a .5 was probably reasonable and showed it could detect some mid range results as well I wish they were cheaper but they seem to be a fairly worthwhile rapid test. I’m ordering another set now

Inaccurate. Flaw in design.
The plastic covered on top of the paper strip is so thick. It prevented the water to sip into the paper part of the strip. These 3 are from the same water. Only if you pop the top plastic to expose the paper, you won’t have a n accurate reading.

Work fine
I liked these strips, no different than any other name brand. Did the job I expected.

I aint sure it is measuring anything. Use is easy but i am not sure the band really interacts with the water in an efficient way. But the fishes are alive.

I bought these along side API 5 in 1 strips so I would be able to read all the necessary water quality readings. They seem pretty accurate so far, and are super easy and quick to use. I love these compared to the liquid ones with drops of chemicals. Way faster and way easier to read! I would definitely recommend these for water testing!

Convenient, accurate as tested against API master liquid test kit and results are fast. Helps keep your fish healthy by monitoring and quickly checking ammonia levels. Although they are expensive and I would recommend a liquid test kit over these but good to have if in a rush and you don’t have time to get your master test kit out.

Bought these as well as the ammonia test kit. Didn't know which one I'd like best .both are good and very accurate.
