Ensure the safety of your aquarium with Ammonia Alert®, the most efficient and long-lasting ammonia detection device on the market. Using Seachem's advanced sensor technology, this compact device provides real-time ammonia monitoring without the need for test kits, chemicals, or manual procedures.


Key Features

Continuous Ammonia Detection – Monitors free ammonia 24/7
No Test Kits or Chemicals Required – Just place it in the aquarium for instant readings
Reversible Color Sensor – Changes from yellow (safe) to green to blue (toxic)
Highly Sensitive – Detects ammonia levels below 0.05 mg/L (ppm)
Long-Lasting PerformanceWorks for over a year, outlasting competitors by 9X
Compact & Unobtrusive – Almost half the size of competing products
For Freshwater & Marine Use – Ideal for all aquariums


How Ammonia Alert® Works

Real-Time Monitoring: The sensor continuously detects free ammonia and changes color accordingly
Fast Response: Detects increasing ammonia levels within 15 minutes
Slower Reversal: After ammonia removal, it takes about 4 hours to revert from TOXIC to SAFE
Accuracy & Sensitivity: Works best under natural daylight or daylight-simulating lights


Ammonia Alert® Color Interpretation

Color Status Free Ammonia (mg/L) Recommended Action
🟡 Yellow SAFE < 0.02 No action required
🟢 Green ALERT 0.05 Monitor closely; water change recommended in 3-5 days
🔴 Red ALARM 0.2 Water change needed within 1-3 days
🔵 Blue TOXIC 0.5 Immediate action required – perform a water change or use AmGuard™

💡 Did You Know?

  • Free ammonia is far more toxic than ionized ammonia
  • At pH 8.3 (marine), ALERT corresponds to 0.25 mg/L total ammonia
  • At pH 7.0 (freshwater), ALERT corresponds to 3.6 mg/L total ammonia

Product Care & Maintenance

🚫 Avoid touching the sensor – Skin oils can reduce sensitivity
🚫 Do not clean with bleach, detergents, or abrasive materials
To remove algae, gently wipe with a soft, clean material
Check sensor response by holding it over an ammonia bottle – it should rapidly change color
Drying out does not permanently damage the sensor – Sensitivity may even improve over time
