5. here comes a lot of text
The swimming pool exterior/container for the water is
usually made out of plastics and cements. The pool water itself
has a small level of chlorine, with cyanuric acid as a stabilizer.
Calcium hypochlorite is also used to “shock” bacteria that
chlorine doesn’t catch. Sometimes, Bromine is used instead of
Chlorine. It works better, but costs more. Obviously, one of the
main ingredients in pool water is water (or H20). Without
chlorine in pools, pools would constantly be bacteria-ridden.
Chlorine is usually found buried under the surface of the Earth in
rock salt or halite, where water is found all over the world.
Bromine is found in the earth’s crust (and in seawater). Not
much Chlorine is used in swimming pools, at least not enough
for it to be deadly. Water is usually not deadly by itself, except in
cases of suffocation.
