GH FRESHWATER TEST KIT
A correct General Hardness (GH) is essential for clear water. GH is a measurement for the total amount of dissolved minerals in the water; these minerals mainly consist of Calcium. These minerals are essential for the well being of your fish and plants.
The best GH value in freshwater is between 8 and 12, when it is above 15 it is too hard and white lime deposits can occur. This can be damaging to pumps and internal filters as deposits may cause the pump or filter to cease.
