Okay you guys are really freaking out for no reason about poop in a pool!
A pools filter should turn over the pool in X number of hours...in that X 90% of impurities are taken out of the water, and this is BEFORE chlorine or bromine comes in to play..
Take this for instance.
One of the pools I run, the Chlorine and PH are on the dot....8 sand filters are on 24/7....someone poops in the pool, I vacuum the poop/pool....within 4 hours, my 500,000 gallon pool has turned over 1 complete time. Meaning every gallon of water in the pool has run through the filters...not even to mention the thousands of gallons that are going through my vacuum filter....in 8 hour- the pool's been filtered twice.
Most states do not have laws for fecal material in a pool (public pools etc.)...HOWEVER even though VT does not, I go by the NPSI and close my pools down for 24 hours...and I DO NOT shock my pool during tha time. If your chemicals are on the dot to begin with, and your filters are running...no reason to shock.
Sorry to sound so snooty, but I'm more than qualified to tell you what I"ve told you, I'm not only a family pool owner, but a AFO/CPO, nationally certified
