Shrimp Tank GH General Hardness General hardness abbreviated as GH is also known as water hardness. GH is simply the measure of the total salts contained in your aquarium water. Calcium and magnesium are the primary salts dissolved in hard water.
The shrimp tank is a confined environment where waste (urine, excrement, plant debris, excess food, dead fish) is constantly released into the system. These nitrogen products are quickly degraded and transformed into ammonia (NH3), soluble in water, and invisible but which is very toxic to shrimp. The nitrogen cycle represents the transformations that the ammonia will undergo to be finally degraded into nitrates, which is less toxic.
