Ugh! Whoever would want to swim in such a concentrated salt solution? That would suck the water out of your skin in no time. I used to live near the Great Salt Lake. Nobody swims in it because it's scummy from algae which do very much survive and love highly salty water. I'm having a great time picturing 32,000 pounds of water in a 13,000 gallon round pool, imagining the salt sliding out of the dump truck, making a tall mound of salt in the middle. Catfish on top of it with a big rake pushing the salt into the water which, of course, is overflowing the sides. What stays in is getting very cold due to the exothermic reaction. Catfish is now up to his ankles in a supersaturated, very cold salt solution and we see the flesh dissolving off his feet . . . okay, I'll stop.

BTG has a good idea: try it in your bathtub, first. Sit in it for an hour or so, see what it does to your bottom. Ouch!
