Can't fight City Hall! Do what you gotta do.

However, "runny poo" is not a symptom of chlorine over exposure.

In your last post, you mention opening cloudy, but earlier you'd mentioned cloudy in the AM -- different, unrelated problems. Which are you trying to solve? Cloudy in the spring, or cloudy in the morning? I thought it was the latter; if it's the former, we've been on the wrong track.

Regarding your chlorine demand -- if you have heavy lotion load (and it sounds like you do) and you have frequent peeing in the pool (and I suspect you do), 5 ppm loss per day is not surprising, so the PM to AM drop may be normal for you, and your pool.

If your pool is clear now, go ahead and let it drop (as if you have a choice ), but stop the drop at 15, and then hold the 8 - 15 ppm level you need for 100 ppm CYA. If that's intolerable to City Hall, you'll have to drain and refill till you get your CYA down to 40 ppm or so.

BTW, I'm 99% sure your poo issues have nothing at all to do with your pool issues. But, as I have always told my commercial customers here, even when the health inspector is wrong, they are still the inspector, so if we can we go along!
