Seachem Ammonia Alert is an innovative color device for continuously detecting and monitoring free ammonia in aquariums. A sensor changes from yellow to green to blue, relative to the ammonia concentration in the water. Seachem Ammonia Alert detects less than 0.05 mg/L (ppm) free ammonia and alerts you before fish show any signs of stress. It lasts over a year and replacement sensors are available.

  • Easy visual gauge to monitor ammonia in your reef or fish tank
  • Use in saltwater or freshwater aquariums
  • Provides 1 year of ammonia detection

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 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 register a SAFE reading.
