Somebody was asking me about how I kill the algae in my fountain and I told them I don't. I said occasionally I'll put bleach in it which seems to turn in from a green to a grey I said since the fountain doesn't have a filter, it's not going to work the same as when I put bleach in the pool. Some woman at the party immediately acted in HORROR. "You mean, you put bleach in your pool? Like the kind you clean your bathroom with?" I thought she saw the devil or something. I went on rambling about bleach vs. pucks and CYA but probably sounded like I was speaking another language. How often do you get these reactions?
