The part of the total hardness that is formed by the ions of carbonates(Co3) and hydrogen carbonate(HCo3). It is symbolized by dCH. It is important to know the dCH of your water, as it affects both the ph. and Carbon Dioxide amounts in your water. It is also commonly called "buffering capability". a dCH of 4 to 8 is fine for most fish.
A measure of carbonates and bicarbonates dissolved in the water. It is measured in degrees of hardness. Indicates the pH buffering capacity of the water.
carbonate water hardness. Compare with water hardness. Water hardness due to the presence of calcium and magnesium carbonates and bicarbonates. The "noncarbonate hardness" is due mostly to calcium and magnesium sulfates, chlorides, and nitrates.
The hardness in water caused by carbonates and bicarbonates of calcium and magnesium.
Hardness in water caused by bicarbonates of calcium and magnesium. If alkalinity exceeds total hardness, all hardness is carbonate hardness; if hardness exceeds alkalinity, the carbonate hardness equals the alkalinity.
A measure of the total amount of both magnesium & calcium carbonates dissolved in water...excluding other salts.
That hardness in water caused by bicarbonates and carbonates of calcium and magnesium.
Water hardness due to the presence of calcium and magnesium carbonates and bicarbonates in water; the smaller of the total hardness and the total alkalinity.
Carbonate hardness is the measure of the carbonate (CO32-) and bicarbonate (HCO3-) ions contained in a solution, usually water. It is usually expressed either as parts per million (ppm or mg/L), or in degrees (KH - from the German "Karbonathärte"). One German degree of carbonate hardness is equivalent to about 17.8575 mg/L.
