Basic Hardness (GH) and Carbonate Hardness (KH) are measures of mineral content material in aquarium water, particularly calcium and magnesium for GH, and carbonates and bicarbonates for KH. Elevated ranges can create an unsuitable setting for sure fish and crops, hindering their progress and general well being. Sustaining applicable GH and KH values is essential for a thriving aquatic ecosystem.
Controlling mineral content material is essential for a number of causes. Some fish species originate from smooth water environments and can’t tolerate excessive GH. Equally, excessively excessive KH could make pH administration troublesome, resulting in instability and stress for aquatic life.
