Seachem Ammonia Alert Permanent Test for Freshwater & Marine Aquariums

Seachem Ammonia Alert Permanent Test for Aquariums

Continuously monitor free ammonia in freshwater and marine aquariums with no test kits, chemicals, or procedures needed. This sensor provides constant readings for over one year, detecting levels as low as 0.05 mg/L to alert you before stress occurs. It responds in about 15 minutes and is small, clear, and discreet to avoid disrupting your aquarium view. Ideal for preventing ammonia toxicity, it shows warning colors for safe, alarm, or toxic levels, with slower reduction response. Use in marine or fresh water, but not recommended for acidic pH. For emergency removal, treat with AmGuard.
