Seachem Ammonia Alert
Seachem 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 and is suitable for both marine and freshwater aquariums.
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 free ammonia is detectable continuously with a responsive color change.

I’ve used the Ammonia Alert for over six months in my freshwater tank. The color change is clear and easy to monitor. I noticed a shift from yellow to green early on, which helped me catch a spike before my fish showed any signs of stress. No water testing required, which saves time and effort.

This device works reliably. I keep it in my 100-gallon marine tank and can see the color change from green to blue when ammonia levels rise. It’s a simple, effective tool that gives real-time feedback without needing chemicals or test kits.

The sensor is easy to install and the color changes are noticeable. It took about five days to stabilize after first use. I appreciate that it doesn’t require any water sampling or procedures. A little slow to respond initially, but once equilibrated, it’s very accurate.
