Good point — the contents label is your friend. However, pool water can be swallowed in large quantities, so algeacides are at low levels, only. The chlorine is the primary algeacide.

Pool water is safe to use for washing but it really shouldnt be used for drinking. Without electricity the water will quickly turn to green gunk and unsafe to drink.
Many pool shocks and other cleaners have chemicals besides chlorine which are bad for you.
But hey, each to their own.
