Sera Test NH4/NH3 - Ammonium/Ammonia - Drop test

To easily determine the concentration of ammonium and ammonia in fresh water and sea water.

Ammonium and ammonia come primarily from fish droppings. They can transform into each other, depending on the pH value. While ammonium is virtually harmless, ammonia is toxic to fish.

Will be NH ₄ /NH ₃ test makes it possible to determine the total concentration of the two (the attached table makes it possible to note the effective content of ammonia according to the pH).

Sufficient for about 60 measurements.
