NOT MY POOL, my parents' pool. This was an issue last year, several grandkids, just the boys had sore and kind of raw boy parts after swimming on and off for the day. My dad said his cholorinator wasn't working properly, and he was over cholorinated and that has since been fixed.
He uses tabs, I'm talking to him about BBB and TFP and testing, he is slowly picking things up. Anyway, today he had us over for a BBQ, after a few hours one of the boys started complaining, my dad insisted he tested (using a cholorine/ph drop test) and levels were fine. I chalked it up to one of the kids being dramatic remembering last year's incident. Then my son started hurting but he didn't even want to stop swimming, when I took him in to change him you can tell his area was irritated. My parents are so upset, I tested his water with his test, cholorine was at about 3 and ph was low under 6.8. He said he added PH up (either last night or yesterday I'm not sure which).
I know it is not a bathing suit, issue because it's happening to multiple kids, my son never has an issue with our pool or any other pool for that matter. The adults were fine but they were not in the pool for the amount of time that the kids were. Can anyone help tell me what this could be.
