Hey, former lifeguard here!
My partner is trained as a pool operator, and we both have pretty intimate knowledges of how pool filtering and operation works. Something, first off, to know is that pools are ABSOLUTELY filthy. Chlorine levels are severely impacted by dirt and debris (which is also why you absolutely must shower before you enter a pool) and the more dirty people in a pool, the more chlorine is bonded with that dirt and the lower the chlorine level gets. Other chemicals like bromine destabilize when they’re oxygenated (in this case, water movement oxygenates bromine) and that chemical is released, also throwing off pool chemicals.
Dirt doesn’t magically disappear once you enter a chlorinated pool- it stays in there. I know you didn’t really want to think about all the sweat, urine, feces (because lets face it, kids are bad at wiping at traces remain on the body, coming off in the pool) and dirt you’ve been essentially swimming around in at every pool you’ve ever been to in your life, but that’s the truth of it. That’s why pool staff are adamant about shoes OFF on deck and people showering before you get in.
Plus, I don’t trust people with pools in their backyards for ONE SECOND to be maintaining proper pool chemistry. All of these nasty ass parents are letting their kids sit in their filth for days on end. Above is correct- you HAVE to wash chlorine off.
TL;DR : chlorine doesn’t fix everything, you have to shower before and after being in a swimming pool, and all these facebook parents are fucking disgusting.
