Seachem Ammonia Alert is an innovative color device designed for continuously detecting and monitoring toxic free ammonia (NH3) in both freshwater and marine aquariums. Unlike traditional test kits that only provide a "snapshot" of water quality, this sensor stays in the tank and changes color to alert you to rising ammonia levels in real-time. It is the only ammonia monitor on the market that detects the truly toxic free ammonia, ignoring the non-toxic ionized form (NH4+) that can lead to "false positives" in standard kits.
Ammonia Alert provides a critical early warning system to protect your fish from the #1 killer in home aquaria.
Continuous Monitoring: Provides 24/7 visual updates on your ammonia status without the need for messy reagents, test tubes, or wait times.
Detects Toxic Free Ammonia: Specifically tuned to detect the gaseous NH3 that causes gill damage and stress, rather than the total ammonia (NH3 + NH4+) measured by most kits.
Long-Lasting Sensor: The specialized sensor membrane is designed to last for over one year, providing incredible value and long-term peace of mind.
Color-Coded Scale: Features a clear, easy-to-read scale: Yellow (Safe), Green (Alert), Blue (Alarm), and Purple (Toxic).
Compact & Discreet: Small enough to be placed in a corner of the aquarium or inside a sump where it won't distract from your aquascape.
How quickly does the Ammonia Alert respond?
The sensor typically responds to a rise in ammonia within 15 minutes. A decrease in ammonia (after a water change or treatment) may take up to 4 hours to reflect on the sensor.
Does it work in saltwater?
Yes! Ammonia Alert is equally effective in freshwater and marine environments.
Why does my test kit say I have ammonia but the Alert stays yellow?
Most liquid test kits measure "Total Ammonia," which includes non-toxic NH4+. If your pH is low, most ammonia is non-toxic. The Ammonia Alert only turns green/blue when the toxic form is present.
Seachem Prime: Keep Prime on hand to immediately detoxify ammonia if the Ammonia Alert moves into the "Alert" or "Alarm" zones.
