Hanna Marine Ammonia Checker

Handheld Checker for Marine Ammonia - HI784

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.

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.
