Ammonia Alert from Seachem is an innovative colour-based device for continuously detecting and monitoring toxic free ammonia. | The product works when a sensor changes reversibly from yellow to green to blue, relative to the ammonia concentration. No test kits, chemicals, or procedures are needed. The device detects less than 0.05 mg/L (ppm) free ammonia and alerts you to the #1 killer before any sign of stress. It lasts over a year and is suitable for marine or freshwater use. Ammonia Alert lasts over 9 times longer than competing products. It's small, clear, and unobtrusive, so it won't detract from the view of your aquarium.
