I found a rat in the pool going for his morning swim this morning. So I scooped him out and tossed him into the woods in the back. Do I need to shock or anything like that? I did a quick search, and most people seem to think it's a problem only if the critter has been dead and sitting in the pool a while. If I don't need to shock, would it hurt anything to add some anyway? My wife is insisting we change our water lol, she's a little freaked out...I'm trying to convince her otherwise.
