Hanna Checker – Marine Ammonia NH3/NH4*
The HI784 Marine Ammonia Checker HC is a handheld colorimeter that uses the Beer-Lambert principle to determine the concentration of ammonia colorimetrically .
The HI784 is designed specifically to measure ammonia levels in a saltwater aquarium . The 0.00 to 2.50 ppm range is ideal for coral/fish or fish-only aquarium maintenance.
Ammonia is a by-product of the Nitrogen cycle. Ammonia is normally removed by nitrifying bacteria , but ammonia levels can rise if there is an imbalance in the tank water chemistry . Excessive ammonia in a marine aquarium increases the risk of inhabitant illness or death..
