CLEANLINESS IS NEXT TO GODLINESS

[cannongal]

Spas too, have AU water!

Ok, I tried to Google au water to find out what the fuck you are talking about,  but I don't live at Auburn university or Australia,  so please tell me what you're talking about?

Already Used water!

It's not changed after every use right?

Ok, that I can understand.    My hot tub is my own, it's not used by the public,  just my family.   Not really concerned about it,  because we test every day and add the appropriate amount of chemicals to sanitize it.   

I take it that you have never been in a public pool? (At a resort or otherwise).  You do realize that they dump enough chlorine in there to bleach your clothing and hair,  there's no fucking chance that you are going to catch something.
