I agree with the person who suggested there should be an adult pool and a child's pool next to it rather than having the two combined. If a child should, by accident, poop in a pool there are laws that govern what must be done next. When we owned a condo on the beach which had a pool if a child had an accident the pool had to be completely drained, cleaned up with strong cleaner and then refilled. I believe, but not positive this was also a Florida Heath Dept. mandate. It's one thing to correct the problem in a child's pool vs a large adult pool! There were attempts to control this exposure by setting age limits to use the pool, no child without a diaper would be allowed, etc, etc. but some parents would insist they wanted their child in the pool and bingo it had to be closed and drained. Just a thought.
