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).
The earliest known camel, called Protylopus, lived in North America 40 to 50 million years ago (during the Eocene). It was about the size of a rabbit and lived in the open woodlands of what is now South Dakota.
