If it's too high, your water might get cloudy, or you might get scale at the pool's water line or inside the pool heater.
If it's too low, it can cause the surface of a concrete pool to erode.
If it's too low in a vinyl or fiberglass pool, it will have no effect, so don't worry about it.
Pool dealers will still sell you calcium to add to vinyl pools, because they like selling stuff, and have been told by the chemical companies that you need to have it. They don't know why, though.

Can you use sodium chloride rather than calcium chloride in fresh water swimming pool for hardness?
No, because it's not the chloride part that's responsible for the hardness, it's the calcium. Sodium chloride is actually used in water softeners, so it's not a great choice if you're looking to increase the hardness. You could use calcium hydroxide, though this will also make the pool more alkaline which may not be ideal.
What tools would be required for testing the chemicals in a swimming pool?

Is swimming in the sea healthier than swimming in the swimming pool?
One is not necessarily more healthy than another, because it depends on the sea and it depends on the swimming pool. Ocean conditions vary tremendously depending on the weather, currents, and other variables. When evaluating the health of a swimming pool, you need to look at how well it's maintained. A sanitized swimming pool (usually with chlorine) that is balanced (meaning pH, alkalinity, calcium hardness, etc.) is safe for swimming. If the pool hasn't been properly sanitized and balanced, swimmers are vulnerable to ear and eye infections and other problems caused by bacteria and other contaminants in the pool.
