Seachem Ammonia Alert Sensor (Pack of 2) | Continuous Ammonia Monitoring for Freshwater & Marine Aquariums

The Seachem Ammonia Alert Sensor (Pack of 2) offers continuous, real-time monitoring of toxic free ammonia in both freshwater and marine aquariums. This innovative device eliminates the need for test kits, chemicals, or procedures. Its sensor reversibly changes color from yellow to green to blue, directly correlating to the ammonia concentration. It detects free ammonia levels below 0.05 mg/L (ppm), providing a crucial early warning against the #1 killer of aquarium fish before any signs of stress appear. The sensor is designed to last over a year, offering reliable, constant readings for the health of your aquatic environment.

In the absence of free ammonia, the unit typically displays a yellow or faint yellow-green color. It's normal for a dry sensor to have a greenish hue, and it may take up to a few days for the sensor to fully equilibrate with the aquarium water. The continuous detection provides a response time of about 15 minutes to increasing ammonia levels. While the response to decreasing ammonia is slower, requiring approximately 4 hours to indicate safe levels upon ammonia removal, the constant monitoring ensures you are always aware of potential dangers.

For Indian aquarists, this imported Seachem Ammonia Alert provides peace of mind against fluctuating tap water ammonia levels or issues arising from overfeeding or decaying organic matter. Unlike local alternatives that may require frequent testing, this sensor offers a set-and-forget solution. All customs duties and GST are included in the listed price, and delivery is handled via ExpressBox tracked shipping, ensuring your order arrives safely and efficiently.
