Seachem Ammonia Alert Aquarium Monitor (1 Year)

Keep a constant check on your aquarium's water quality with the Seachem Ammonia Alert, a continuous ammonia monitoring device that provides peace of mind for freshwater and marine aquariums. Designed to last for up to one year, this easy-to-read sensor continuously monitors toxic free ammonia without the need for test strips or liquid test kits.

The colour-changing indicator responds to free ammonia levels in real time, helping you quickly identify potentially harmful conditions before they become dangerous to your fish. As it only detects toxic free ammonia (NH₃), it won't give false readings from the safer ammonium (NH₄⁺) commonly found in established aquariums.

Simply place the Ammonia Alert inside your aquarium or filter, and it will continuously monitor water conditions with no batteries, chemicals or maintenance required.
