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).
Another species, the Arabian camel (Camelus dromedarius), has one hump only. Both animals hauled goods along the Silk Road. Bactrian camels are fit for the cold climates of Central Asia, Mongolia and China, and were commonly used on the eastern trade routes. Arabian camels were more likely to be used on the western routes.
