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.
