Seachem Ammonia Alert Continuous Ammonia Monitor

The Seachem Ammonia Alert provides continuous monitoring of toxic free ammonia in freshwater and saltwater aquariums. Its reusable sensor changes color as ammonia levels rise, giving aquarium keepers an easy-to-read warning without test strips, chemicals, or water samples.

Simply place the monitor inside the aquarium or filter where it can be viewed easily. The center sensor changes from yellow to green and then blue according to the concentration of free ammonia in the water. Each monitor lasts for over one year under normal aquarium conditions.
