Rated 5 out of 5 by Retiredprofessor Biochemistry of ph/ammonia alert
Animals (fish, snails, coral, etc) produce ammonia (NH3) as a waste product. Ammonia is a very reactive chemical which is toxic to living organisms. Based on the pH of the environment, ammonia is converted automatically to the ammonium ion (NH4), which is much less toxic (high pH: more ammonium, low pH: more ammonia). A specific bacterial organism converts ammonia/ammonium to nitrite which is also toxic to living organisms. A second specific bacterium then converts the nitrite to nitrate, which has low toxicity. Water changes and/or charcoal elements in your filter then remove the nitrate. Ammonia alert specifically measures the level of ammonia (NH3)! All of the other test kits measure ammonia PLUS ammonium, so you don't know if you actually have a problem! Water conditioners like "Prime" bind ammonia, nitrite, and nitrate to lower toxicity, BUT all of those will be detected with test kits (plus chloramines added by your water department). Therefore, using the ammonia alert will instantly let you know if there is FREE AMMONIA (TOXIC), whereas using a test kit will only tell you the TOTAL amount of nitrogen compounds! These small detectors attach with supplied suction cups to the inside of your aquarium and last for approximately a year. VERY useful and well worth the cost!

I purchased two of these kits to help monitor a few of my tanks in between water testings/changes. Two of the tanks had recently been moved and one had had a large bio load placed on it. I just knew that these detectors would pick something up. I couldn't have been more wrong.
On one of my goldfish tanks, the ammonia detector didn't detect a thing, but my water test kit said my ammonia level was .25ppm. And in that same tank, the ph detector said my water was in the 6.2-6.6 range, when an actual test of the water showed that it was somewhere between 7.6 and 8.0.
Considering the second ph detector is reading almost the same as the first one, and the water is from the same source, I'm going to assume that both of the detectors don't work, and I didn't just buy one faulty kit. I'll test that water once I finish my work with the first goldfish tank, but I think it's pretty safe to say that this kit is junk. It does not perform like it's supposed to, it does not act as an early warning to changing water conditions, it's just a waste of money. :(
