Seachem Ammonia Alert
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.
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 (1.5" x 2.5"). It's small, clear, and unobtrusive, so it won't detract from the view of your aquarium.
No strips, no tests, just constant readings. Lasts 1 year.
Not recommended for use at pH 6.0 or below.
