Seachem Ammonia Alert is a revolutionary sensor tag that continuously monitors toxic free ammonia levels in both marine and freshwater tanks. Using a color-changing sensor that shifts from yellow to green to blue, it provides real-time, chemical-free detection of ammonia concentrations as low as 0.05 mg/L. Designed for effortless, hands-off use, it lasts over a year and alerts aquarium managers early to prevent fish stress and fatalities, making it an essential tool for proactive aquatic care.

## Description

Ammonia Alert is an innovative color device for continuously detecting and monitoring toxic free ammonia. A sensor changes reversibly from Yellow to green to Blue, relative to the ammonia concentration. No test Kits, chemicals, or procedures are needed. The device detects less than 0.05 mg/L (ppm) free ammonia and alerts you to the #1 killer before any sign of stress. It lasts over a year. Marine or freshwater use. In the absence of free ammonia the unit will assume a Yellow or faint yellow-green color. It is normal for the dry sensor to have a greenish hue. It may take up to a few days for a dry sensor to equilibrate with the water. No sampling of water, chemicals, or test procedures are required. The presence of the free ammonia is detectable continuously with a Response time of about 15 minutes. Response to decreasing ammonia is slower, requiring about 4 hours to go from toxic to safe on removal of ammonia.

Review: Excellent But Misunderstood Product - I was so worried about purchasing this ammonia reader due to the amount of bad reviews. However, after doing tons of research and deciding to purchase it after all, I realized that a lot of the negative reviews were because people weren’t quite understand just exactly how the Ammonia Alert operates. It measures the amount of unionized (dangerous) levels of ammonia in the water, whereas test kits measure both the ionized (safe) and unionized (unsafe) ammonia present in the water. Therefor, the only reading you’re getting on the Ammonia Alert is that of the toxic ammonia present in your tank. This product definitely works. A few days ago, the reading on it was at the ‘Alert’ mark, which it turned a pastel green. Then, when I checked it today, it was a pastel yellow and definitely matched the ‘Safe’ zone on the wheel. Even though the color readings can be extremely subtle, they’re pretty easy to pick out when it changes. I also compared its reading with a quick test from the API ammonia test kit, to which it came back with 0 ammonia in my aquarium. Another thing I must add is that you MUST be extremely careful when you open up the product. When you remove the plastic covering for the sensor in the middle of the color wheel, do not touch the sensor with your fingers. The oils from your fingers could affect or ruin your sensor. Overall, I’m extremely pleased with this simple and cheap product. It will assure me that my fish are living well and I can take necessary action when it goes into the ‘Alert’ zone. I definitely recommend the Ammonia Alert if you’d like to monitor your aquarium’s ammonia levels while avoiding frequent water testing.
Review: Get It - It's Worth The Investment - I've read all kinds of pro and con "opinions" on this product. It doesn't work - it doesn't match the API Ammonia Test result - and so forth. Well, in my experience it does work. And it's already alerted me to ammonia spikes in two of my aquariums - well before they became a problem. It detects free ammonia which is the most harmful form (API detects free and bound ammonia and that's why they may not agree). It lasts for a year. It reverts back to negative when the problem has been corrected. It's less expensive, much easier to use and just as reliable as other methods. I have it in all four of my aquariums. I check it daily and I no longer do ammonia tests. Do yourself a favor and get this. Oh - and read the instructions or try watching one of the available videos on how to properly use it.

### ⭐⭐⭐⭐⭐ marine biology phd, it works
*by K***Y on February 27, 2025*

i was hesitant to buy this because of some bad reviews and didn't want to "take the easy way out" of testing my saltwater tank's ammonia when it could potentially be inaccurate. however, after biting the bullet and about a week of having it in my tank, i can say it definitely works and is accurate. JUST MAKE SURE YOU DO NOT TOUCH THE SENSOR IN THE MIDDLE AFTER PEELING THE PROTECTIVE PLASTIC. also, this measures the amount of TOXIC ammonia only, so the colors won't match perfectly with a water test kit, which tests for the presence of all ammonia (normal and toxic). this is a must have in all tanks, especially the smaller ones where water conditions are harder to maintain. i am a marine biology phd and lifelong tank owner, and i would 10/10 recommend this to anyone (but especially the newbies!). i'm not sure of the shelf life, but i will probably switch out every 6-12 months to be safe. 👍🏼🐠🪸
