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 Bactrian camel has two humps on its back, as does the wild Bactrian camel (a separate species), but in contrast to the single-humped dromedary camel.[2] Its population of two million exists mainly in the domesticated form.[3] Their name comes from the ancient historical region of Bactria.[4]
