I first want to thank you very much for this website. It has been an invaluable tool for us and with the recommended pool chemistry kit we buy, we have had absolutely zero issues with our pool since start up. I haven't been on here in a very long time and I'm sure this question has been answered somewhere already but I am pretty desperate to find an answer asap. My question is, how high FC is too high to swim in? We are hosting swimming lessons this week and my husband accidentally put too much chlorine in the last couple of days and the FC is now at 12. We have never had it this high as usually we keep it balanced. Is 12 ok for kids to swim in??
Thanks in advance!
