Seachem Ammonia Alert In-Tank Monitor
Seachem Ammonia Alert is a simple, in-tank aquarium monitoring device that continuously detects toxic free ammonia, also known as NH3. This compact sensor attaches inside the aquarium and provides an easy-to-read color indicator so aquarists can quickly spot changing ammonia levels before they become dangerous for fish.
Unlike traditional test kits that require water samples, reagents, or test strips, Ammonia Alert works around the clock for up to one year. It is a helpful tool for freshwater aquariums, saltwater aquariums, reef tanks, quarantine systems, breeding setups, and new tank cycles.

Why Ammonia Monitoring Is Important
Ammonia is one of the most dangerous water-quality issues in aquariums. Even small spikes can stress or harm fish, especially in new tanks, quarantine systems, overstocked aquariums, or tanks with disrupted biological filtration.
Using an in-tank ammonia monitor helps aquarists detect possible problems sooner, monitor cycling progress, catch filtration failures early, and provide added peace of mind between regular water tests.
How to Use
- Remove the Ammonia Alert from the package.
- Place it inside the aquarium where it can be easily viewed.
- Allow time for the sensor to adjust to the aquarium water.
- Compare the color indicator to the guide on the product packaging.
- Replace after approximately one year or according to manufacturer recommendations.
Important Use Notes
- Ammonia Alert detects toxic free ammonia, not total ammonia.
- Use regular water testing for a complete view of aquarium water quality.
- Respond quickly if ammonia levels rise.
- Keep the sensor visible and clean for easier reading.
- Regular water changes, proper filtration, and careful feeding are still important for ammonia control.
