Not the water perhaps?
Hello~
Glad you had a successful party~
It is very possible that the alleged dry itchy skin had nothing at all to do with your pool water. Was your own skin dry and itchy?
Some people have dry skin. I have dry skin, now that I'm older. I've never been to Arizona, but don't folks like it there because it is not humid and jungle-like? Seems to me that some people will suffer from dry skin in Arizona.
Also some people are a little neurotic and just knowing they were in a pool that has--OMG--chlorine in it is enough to start them scratching.
The above posters' water-enhancement ideas will be something you might appreciate doing for yourself, and the next time around, you might mention to your friends that you have added some special products to your water just for them! :-D
Happy Swimming~
