Seachem Combo Alert uses Seachem water sensor technology to continuously monitor ammonia and freshwater pH in your aquarium for an entire year, with no tests or strips required. All you have to do is hang it in your tank!
- Continuous freshwater pH and ammonia readings
- No strips, no tests, just constant readings
- Easy monitoring – hang it in your tank
Ammonia Alert: The sensor automatically detects free ammonia at levels less than 0.05 mg/L (ppm) and alerts you to the presence of the primary killer of fish before it reaches hazardous levels and causes signs of stress. Without free ammonia, the sensor will assume a yellow color and move to green and blue as more ammonia is detected. Ammonia is detected continuously with a response time of just 15 minutes, allowing you to respond immediately and avoid further increases. Ammonia Alert lasts nine times as long as competing products and is only about half the size.
