Overview

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. This product is not recommended for use at acid pH. 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.

Ammonia Alert® lasts over 9X as long as competing products.
Ammonia Alert® is also almost half the size of competing products. It’s small, clear, and unobtrusive, so it won’t detract from the view of your aquarium.

Seachem Ammonia Alert for Singapore Aquariums

Seachem Ammonia Alert is a small adhesive sensor that sits inside the tank and changes colour with free ammonia, giving you a continuous at-a-glance reading rather than a once-a-week test. We find it especially reassuring during the first weeks of a new tank, when the nitrogen cycle is still establishing and ammonia is the parameter most likely to harm fish before you spot any outward signs of stress.

In our warm SG tanks biology moves quickly, which cuts both ways: cycles can establish fast, but a missed water change or an overfeed can also push ammonia up between manual tests. A passive sensor on the glass means you notice that shift the next time you walk past, not days later. It works in both freshwater and marine systems and lasts well over a year before it needs replacing.

It pairs naturally with kits from our water testing and care range. Read our ammonia spike guide and the nitrogen cycle for beginners article to understand what the colours are telling you.
