A salt water pool isn’t what you think it is. The “salt” in salt water pools is used to make chlorine via electrolysis. The water itself really isn’t very salty at all, only about 1/10th the “saltiness” of the sea. Basically if you think the water in a salt water pool is like the ocean, you’re incorrect. You would add chlorine to the water if needed, but the chlorine generator (which uses salt to make chlorine) generally keeps the chlorine level in check.
