Our Ammonia Checker® HC (HI784) provides an uncomplicated, highly accurate, and budget-friendly way to measure ammonia (NH3/NH4+) in saltwater/marine environments.


Ammonia is naturally found as part of the nitrogen cycle of a tank as aquarium organisms produce it as waste. In a balanced tank, the majority of ammonia is consumed by bacteria and the nitrogen cycle continues. When out of balance, ammonia toxicity can wreak havoc on tank inhabitants. It is important to monitor ammonia levels to ensure they remain steady and low. The ammonia checker is designed as an exceptionally accurate alternative to chemical test kits, our Marine Ammonia Checker (HI784) provides quick, accurate results in a few easy steps.
