API AMMONIA TEST STRIPS Freshwater and Saltwater Aquarium Water Test Strips 25-Test Box

The ammonia test strips are affective and easy to use. The API ammonia test strips test for both NH3 and NH4. They come in a nice sturdy tube that seals well. Just don’t stick wet fingers in the tube you’ll mess up all your test strips. Just dip for 5 seconds then hold strip level and wait 60 seconds. I recommend using these along side with 5 in 1 API test strips :) very easy and definitely recommend!

Straight forward they work, just dip in tank water wait a minute read test strip against color chart on strip container.

They work! I needed them for my above ground 2,500 gallon above ground pond. They seem quite accurate and I appreciated the instructions.

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

The Best !

I bought the API ammonia test strips hoping to save some time compared to the bottle test kit for random testing. The ranges on these strips go from 0, 0.5, 1.0, 3.0 and 6.0 ppm. The color difference for each range is ever so slight that it makes getting any meaningful result impossible. You can use these to test if you have any ammonia, but the difference between 0 and 0.5 is too small to tell, too. It would be real easy to get 0.5 ppm and think it shows 0, which is unacceptable. You need 1.0 ppm or higher to see a clear result. You will probably have several dead fish by that point. Stick with the bottle kit. It's much easier to read with better color scales.

GREAT PRODUCT. API....ITS ALLLL ABOUT THE FISH:)

use these as a third test check to make sure no nasty ammonia

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.

Set up a new tank recently and used this to monitor the water cycle changes. And it did changed and show the water parameters changes as expected. It may not be 100 accurate but certainly good enough as indicator unless you need point blanc accuracy.

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

Very easy to use for a quick water quality test. May not be as accurate as a chemical test, but lets you find out immediately if there is a problem with your tank. I would definitely recommend this product to anyone with multiple tanks such as I do.

Quick easy and accurate. Gets the job done.
