The earlier measures magnesium and calcium, whereas the latter measures carbonate and bicarbonate ions. When measuring the arduous water for fish, it is named each diploma of hardness (dH) or as parts per million (ppm). A degree of Frequent Hardness (dH) is printed as 10 mg/L CaO, which is the same as 17.85 ppm.

• When the dH is 0 to 6 and the ppm is 0 to 100, the water is delicate or very delicate.
• When the water’s dH is 6 to 25 and the ppm is 101 to 449, it’s barely arduous to arduous.
• When dH is 30 or further and the ppm is 450 or further, the water is taken under consideration “liquid rock,” or very arduous.

Water’s KH is expounded to the aquarium’s pH stage. The higher the KH measurement, the a lot much less the pH of the aquarium will fluctuate—and that’s biggest for the fish.
