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 ionized 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 ionized 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
