General hardness (GH) is commonly overlooked
in many aquariums, but this parameter plays a
very important role in your aquariums overall
health. GH is the total mineral content of
calcium and magnesium in the water. These are
important for various biological functions in fish,
invertebrates, and even plants. Deficiencies of
calcium and magnesium can cause poor growth
and faded colors in fish, molting difficulties in
shrimp, improper leaf development on plants, or
thin, brittle snail shells.
