The ideal range for calcium hardness in swimming pools is 150-400 ppm (parts per million), so if you try to keep your calcium hardness in the midpoint between those two limits, then you should be fine.
This species is assessed as Critically Endangered. The Wild Bactrian Camel is facing a population size reduction of at least 80% within the next three generations (estimated at 45 to 50 years).
There are two chief kinds of camels: (1) the Arabian camel, also called dromedary, which has one hump, and (2) the Bactrian camel, which has two humps. In the past, hybrids (crossbreeds) of the two species were used widely in Asia.
