## Overview

Seachem Ammonia Alert is a revolutionary sensor tag that continuously monitors toxic free ammonia levels in both marine and freshwater aquariums. It provides instant visual alerts through a reversible color change, detecting ammonia concentrations as low as 0.05 ppm. Designed for hassle-free use, it requires no test kits, chemicals, or water sampling, lasting over a year to ensure your aquatic environment stays safe and healthy.

## 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: Works well. Measures toxic portion of total ammonia - Works great. Measured the toxic portion (unbound) of ammonia in your tank 24/7. If it goes up, add Prime to give yourself 24-48 hours to act by temporarily neutralizing its toxicity. Couple this with an API or Salifert ammonia test to test total ammonia (toxic and nontoxic) to figure out how much ammonia you have to eliminate. Water changes, Dr Tim’s One and Done nitrobacter, etc will help you remove the ammonia from the system. Unless you overstocked, then you are cooked lol

### ⭐⭐⭐⭐⭐ Get It - It's Worth The Investment
*by C***R on March 20, 2024*

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.
