Seachem Ammonia Alert
Seachem Ammonia Alert is an innovative colour-changing device designed to continuously detect and monitor toxic free ammonia in both freshwater and saltwater aquariums. The incredibly accurate sensor changes reversibly from yellow to green to blue, relative to the specific ammonia concentration inside of the tank. Ammonia is the #1 killer of aquarium inhabitants and the convenient device detects less than 0.05 mg/L (ppm) of free ammonia and alerts aquarium owners so that they can take the proper measures to lower the ammonia levels.
When free ammonia is not present, the unit will take on a yellow or faint yellow-green colour and is normal for the dry sensor to have a greenish hue to it. There is no water sampling, chemicals or test procedures needed.
| Ammonia Concentration | Color Indicator |
|---|---|
| Less than 0.05 mg/L (ppm) | Yellow or faint yellow-green |
| 0.05 – 0.10 mg/L (ppm) | Green |
| 0.10 – 0.20 mg/L (ppm) | Blue |
FAQ
How does the Seachem Ammonia Alert detect ammonia levels?
The device uses a reversible color-changing sensor that shifts from yellow to green to blue based on the concentration of free ammonia in the water. It does not require water sampling, chemicals, or test procedures.
What is the lowest ammonia level the device can detect?
The Seachem Ammonia Alert can detect free ammonia levels below 0.05 mg/L (ppm).
Does the device require any maintenance or water changes to function?
No, the device is designed to work without water sampling or chemical additions. The sensor is dry and self-contained, and only needs to be exposed to the aquarium water to function.

I’ve used the Ammonia Alert for over six months in my freshwater tank. It’s easy to read and has helped me catch ammonia spikes early. The color change is clear and reliable. I no longer need to rely on test kits.

The device works well and gives a good visual indication of ammonia levels. I noticed the color shift from yellow to green when levels rose slightly. It’s a simple tool that saves time and reduces stress.

I switched from weekly test kits to the Ammonia Alert and it’s been a game changer. The color change is accurate and I can monitor my tank in real time. Very reliable for both freshwater and saltwater setups.
