Right!

The minor differences between our advice isn't going to matter. Both will work just fine. If you go with CYA=30, that's fine. If you go with CYA=40, that's fine too. Jan has a preference for higher CYA levels than I do, but I have a preference for higher chlorine levels....both work just fine, just a difference in our "comfort level".

But I'd swim in Jan's pool without thinking twice and she would in mine (Watermom and Poconos have swum in Jan's pool and in mine)
