Seachem Ammonia Alert
Seachem Ammonia Alert is an innovative colour device for continuously detecting and monitoring toxic free ammonia. To illustrate a sensor changes reversibly from yellow to green to blue, relative to the ammonia concentration. No test kits, chemicals, or procedures are needed. As soon as Seachem Ammonia Alert detects less than 0.05 mg/L (ppm) of free ammonia it will alert you to the #1 killer before any sign of stress. In the long run, lasting over a year. Seachem Ammonia is not recommended for use with acid pH. Marine or freshwater use.
The unit will assume a yellow or faint yellow-green colour in the absence of free ammonia. Also, it is normal for the dry sensor to have a greenish hue. And, it may take up to a few days for a dry sensor to equilibrate with the water. Furthermore, the presence of the free ammonia is detectable continuously with a response time of about 15 minutes. However, the response to decreasing ammonia is slower, requiring about 4 hours to go from TOXIC to SAFE on the removal of ammonia.
Overview:
Ammonia Alert lasts over 9X as long as competing products.
Seachem 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.
Interpretation:
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. Administering a water change should be considered for any indication other than SAFE. The ALERT concentration is tolerated for 3-5 days, ALARM for 1-3 days, and TOXIC is rapidly harmful, requiring immediate attention. For emergency ammonia removal, treat with Seachem AmGuard.
Care:
Remove algae with clean, soft material. Avoid touching the sensor with fingers. Since skin oils can damage it. Do not use bleach, soap, detergents or hard objects to clean the sensor. Some dye medications may discolour the sensor. Don’t let the unit dry out. However, drying does not permanently impair the unit. Sensitivity improves with age. Read the unit under natural daylight or daylight simulating light. Red enhancing light minimizes green and blue hues, decreasing the apparent sensitivity of the unit.
