Seachem Ammonia Alert 1 tag

Ammonia Alert is an innovative color-changing monitor for continuously detecting toxic free ammonia. No test kits, chemicals or procedures are needed — the sensor changes color reversibly from yellow to green to blue as ammonia concentration rises.

Key Features

• Continuous Detection: Detects less than 0.05 mg/L (ppm) free ammonia and alerts you before fish show any sign of stress.
• Fast Response: Responds to rising ammonia in about 15 minutes.
• Long-Lasting: Lasts over a year and works in marine or freshwater.
