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 types of camel, dromedary camels like in the picture that only have one hump, and the bactrian which has two. There are a lot more dromedaries than bactrians in the world. Camels are related to llamas and alpacas.
