Ammonia Alert® is an innovative color device for continuously detecting and monitoring toxic free ammonia. 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. Marine or freshwater use.
- Continuous monitoring for both ammonia and pH in freshwater. - Ammonia Alert provides continuous monitoring of free ammonia levels in the freshwater and marine aquaria and lasts up to 1 year. - pH alert provides continuous monitoring of pH in the freshwater aquarium lasting up to 6 months. - Small and unobtrusive in the aquarium; simply place alerts visibly in the aquarium or filter for monitoring. (3.8 x 6.3cm) - Package contains 1 pH Alert and 1 Ammonia Alert.
Ammonia Alert® lasts over 9 times as long as competing products (over a year compared to 4-6 weeks). Ammonia Alert® is also almost half the size of competing products (1.5" x 2.5"). It's small, clear, and unobtrusive, so it won't detract from the view of your aquarium.
