Quickly and easily check your aquarium’s ammonia levels with API AMMONIA TEST STRIPS. Fish continually release ammonia into the aquarium through their gills, urine and solid waste. Uneaten food and decaying organic matter also add ammonia to the water. Ammonia is toxic to fish and can cause gill damage, stress and death. Regular testing is recommended because ammonia levels can build quickly due to fish waste and uneaten food. Simply dip the test strip into the water, then compare the results with the precise, easy-to-read color-coded chart to determine if any action should be taken. The chart includes recommendations on how to treat the water and neutralize ammonia. Safe for use in fresh and salt water. With API Aquarium products, it’s easy to keep a beautiful saltwater, freshwater or reef aquarium. For over 50 years, API has been creating innovative, research-driven solutions that make it easier to care for your fish and aquarium. API Aquarium Treatment Supplies are designed to work in conjunction with each other to provide best results to control algae, promote healthy bacterial growth and help control and cure fish diseases and conditions such as ich and fin rot. They work to provide a safe, hospitable environment for fish such as tropical community fish, cichlids, goldfish and more. With API, you can spend more time admiring your fish, and less time scrubbing your tank. Make sure to use all products as directed in order to ensure the best results.

Customers say
Customers find the test strips easy to use and of good quality. The functionality and accuracy receive mixed reviews – while some say they work as expected and are amazingly accurate, others report they don’t work at all and are not accurate at all. Moreover, the color accuracy is a concern as the strips never change colors, and readability is also mixed with some finding them easy to read while others say they’re hard to read. Additionally, ammonia levels show dangerous readings for some customers. Value for money opinions are divided between those who find it a good value and those who consider it a waste of money.

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 wellI wish they were cheaper but they seem to be a fairly worthwhile rapid test. Iâm ordering another set now

Works!
Wish it was Abit cheaper

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 wonât have a n accurate reading.

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

Hard for me too read the results
Louis –
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.

Arrived early. So very pleased. Would recommend.

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 donât have time to get your master test kit out.
