Seachem Ammonia Alert. Ammonia Alert is an innovative colour device for your aquarium, continuously detecting and monitoring toxic free ammonia. A sensor changes reversibly from yellow to green to blue, relative to the ammonia concentration.
Ammonia Alert is an innovative colour 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. Marine or freshwater use.
In the absence of free ammonia the unit will assume a yellow or faint yellow-green colour.
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.
Why Its Different
Ammonia Alert lasts over 9 times as long as competing products (over a year compared to 4-6 weeks).
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.
As little as 0.02 mg/L of free ammonia will produce a greenish hue on the detector surface.
This corresponds to a total ammonia (both ionised and free ammonia) of 0.25 mg/L in marine water at pH 8.3. In freshwater at pH 7.0, this corresponds to 3.6 mg/L total ammonia.
Free ammonia is much more toxic than ionised ammonia. As free ammonia, the ALERT colour corresponds to about 0.05 mg/L, ALARM to about 0.2 mg/L, and TOXIC to about 0.5 mg/L.
The ALERT concentration is tolerated for several days, ALARM for a few days, and TOXIC is rapidly harmful. This product is not recommended for use at acid pH
